The rebuff also reveals a changing perception of Facebook in the tech industry. As the once scrappy start-up evolves into a sprawling corporation, younger companies who view themselves as disruptive do not find Facebook’s size and cushy campus as appealing. Not to mention that a lot of them are trying to provide alternatives to Facebook, which means selling to Facebook would defeat their entire purpose.

Despite the site’s primacy in the social media market, some numbers suggest that Facebook addiction has given way to Facebook fatigue, at least among some users. A study by the Pew Internet and American Life Project found that the majority of users have at one point or another taken a multiweek break from the service, citing the tedium and irrelevancy of its content. Among the crucial younger demographic — users ages 18 to 29 — that first propelled Facebook into prominence, 38 percent said they expected to spend less time using the site this year.

The survey confirmed what some at the company already knew. In its latest quarterly call with investors, it said its youngest users were spending less time on the service, although overall teenage engagement was stable.

That fatigue may also have started to trickle down to the developers who build apps on top of Facebook’s platform.

The company’s business depends on the working relationships with those developers. In its early years, Facebook carefully courted app developers like game makers, including Zynga. But it later changed its rules to make it harder for apps to go viral. More recently, though, it has been trying to lure developers back with more favorable terms.
