Americans looking to reduce their reliance on products from tech’s most alarmingly megalithic companies might be surprised to learn just how far their reach extends.

Privacy-minded browser company DuckDuckGo conducted a small study to look into that phenomenon and the results were pretty striking.

“… As Facebook usage wanes, messaging apps like WhatsApp are growing in popularity as a ‘more private (and less confrontational) space to communicate,'” DuckDuckGo wrote in the post. “That shift didn’t make much sense to us because both services are owned by the same company, so we tried to find an explanation.”

DuckDuckGo gathered a random sample of 1,297 adult Americans who are “collectively demographically similar to the general population of U.S. adults” (i.e. not just DuckDuckGo diehards) using SurveyMonkey’s audience tools. The survey found that 50.4 percent of those surveyed who had used WhatsApp in the prior six months (247 participants) did not know the company is owned by Facebook.

Similarly, DuckDuckGo found that 56.4 percent of those surveyed who had used Waze in the past six months (291 participants) had no idea that the navigation app is owned by Google. A similar study conducted back in April found the same phenomenon when it came to Facebook/Instagram and Google/YouTube, though for Instagram the effect was even stronger (wow).

If you’re reading TechCrunch it’s probably almost impossible to imagine that average people aren’t tracing the lines between tech’s biggest companies and the products scooped up or built under their wings. And yet, it is so.

Even as companies like Google and Facebook suffer blowback from privacy crises, it’s clear that they can lean on the products they’ve picked up along the way to chart a path forward. If this survey is any indication, half of U.S. consumers will have no idea that they’ve jumped ship from a big tech product into a lifeboat captained by the very same company they sought to escape.

And for the biggest tech companies, it’s at least one reason that keeping satellite products at arm’s length from their respective motherships is advantageous for maintaining trust — especially while aggressive data sharing happens behind the scenes.
