You might not need another reason to hate Comcast, but here's one anyway.

The nation's largest cable operator is set to begin beta testing its Xfinity TV app for Roku devices later this year. And it's sneaking in a charge that customers will likely find outrageous. In this edition of Ask Maggie, I explain how the charge works and why customers might want to let Comcast know they're not happy about it.

Cable as a whole has long had a poor reputation for customer satisfaction. But Comcast has distinguished itself as among the worst of the worst. The company has repeatedly been called out and humiliated for its employees' treatment of customers.

In 2014, several customers recorded phone calls with Comcast customer service representatives in which the employees verbally abused them. Those got posted to the Internet. Last year, the Federal Communications Commission fined the company $2.3 million for billing and charging customers for premium channels, DVRs, set-top boxes and other products and services they hadn't requested.

Dear Maggie,

I was excited to hear about Comcast's new app that will let you watch TV without a set-top box through a Roku. But then I heard they're still planning to charge customers a monthly fee. What gives?

Thanks,

POed Comcast subscriber

Dear POed,

Here's what's happening. The Roku app will let you watch all the Comcast channels available through your set-top box on a TV that's not connected to a big, ugly cable box. Not only are those set-top boxes unsightly and bulky but they're also expensive. Comcast charges a $9.95 rental fee for each additional box in your home. (The first box is included with the price of your monthly service.) The Federal Communications Commission estimates this costs customers on average more than $230 a year.

The idea of being able to connect multiple TVs, like the TV you might have in your bedroom or the one in your basement, to your cable TV service without paying an additional $10 a month per box sounds like a sweet deal, right?

But not so fast. A Comcast spokesperson confirmed that the company will be charging customers an "access fee" of $7.45 for each TV using the Roku app.

That's the same price Comcast charges customers who use a TiVo or other CableCard device instead of renting a set-top box from Comcast. FCC rules require Comcast and other cable operators to give subscribers a discount if they use a Cablecard device instead of renting a set-top box, which is why the price is discounted for Comcast customers.

What makes this fee striking is that it's not designed to pay for any particular cost to Comcast's business. The $9.95 fee that 99 percent of cable customers pay for set-top boxes is listed on bills as an equipment "rental fee." Even the Cablecard fee includes a bit of hardware from the cable operator. But the Roku app is purely software. It doesn't require a piece of equipment supplied by the cable company, nor does it require a technician to come to your home to set it up.

What's more, Comcast already offers its TV subscribers its Xfinity TV Everywhere app at no additional cost to watch programming on mobile devices like smartphones and tablets throughout their homes. And specific cable channels like ESPN and HBO make their own Roku apps available at no additional charge to Comcast and other cable subscribers, who are already paying for these channels as part of their TV subscriptions.

So why will Comcast charge customers a fee for the app? That's a good question. Comcast declined to answer, saying it's still evaluating its pricing structure before it rolls out the service to all customers later this year.

But Gigi Sohn, who served as a senior adviser to former FCC Chairman Tom Wheeler, said she knows why.

"It's gravy to them," Sohn said. "You're already paying handsomely for the service. And now they're making you pay a second time."

Sohn said this is why Wheeler, who stepped down from the FCC on January 20 when President Donald Trump was inaugurated, was pushing for new rules to open up the set-top box market to competitors. The proposal developed under Wheeler's FCC would have required all cable operators to develop an app to provide their TV programming, but the rules would have spelled out that cable operators wouldn't be allowed to charge customers extra to use the app.

What's more, the rules would have required cable operators, like Comcast, to make the app available to any device platform. This would have meant that not only would the apps be available on Roku devices, they'd also be available on AppleTVs, Amazon Fire TV sticks, Google Chromecast sticks and any other equipment maker's device that wanted to include them.

Those rules got the kibosh earlier this week. New FCC Chairman Ajit Pai removed the proposed rules from a list of items to be considered by the FCC. Pai said earlier this week that the agency is still reviewing them, but given Pai's strong feelings on the matter, experts agree the rules are likely gone for good.

Even without a mandate from the FCC, cable operators could make the Roku app free, and they could offer it on more platforms. In fairness to Comcast, it's only beta-testing the app, so there's a good chance the company will offer apps on other streaming devices. And since beta testers won't be charged for using the app, there's a chance the company could reconsider the fee.

One thing is clear, tacking on yet another fee that only seems to fatten the company's bottom line isn't likely to endear Comcast to customers.
