It’s the official SDK of one of the biggest companies. I can’t fault them on not catching this. What Facebook does is ugly.
I really can't fault Zoom here. They used an existing tool provided by a company that is, allegedly, reputable.
Though, thinking about it more perhaps Zoom should get some more scrutiny here because this isn't the first time Facebook has said eff it to user privacy. Distrust of Facebook should be the default.
There are probably thousands of other apps that have the same problem.
However, it's the Project Managers and Product Owners that are not aware and they say "do it because that's what the customer wants!" and you can argue. You really do so at your own peril if you don't have others on the team to back you up.
People on the team knew, they just either didn’t care or were ignored when they voiced concerns.
