I’d believe it because I remember the same being true for TikTok.
I don’t have the links on me right now, but I remember clearly that when tiktok was new, engineers trying to figure out what data it collected found that the app could recognize when it was being observed, and would “rewite” itself to evade detection.
They noted that they’d never seen this outside of sophisticated malware, and doubted that a social media company had the resources to write such a program.
