Recently downloaded a "cast" app because Miracast doesn't work on GrapheneOS. On first launch, I got 3 consecutive full screen video ads followed by a popup to "subscribe" to their paid service. Next, another popup to rate them 5* in google play store. Note that at this point, I haven't even reached the main screen of the app... You know, to actually try it and see if it works.
Uninstalled that garbage and gave it the 1* rating it deserves.
Seriously, I'm so sick and tired of these "modern" apps which don't even have the decency to offer a good quality paid version. $8/mo for a stupid utility I use maybe a few times a year? Who tf do you think you are?
Using apps on GrapheneOS, I also get notified when they use the play integrity API... I find it insulting when apps like Reddit attempt to access that... Seriously, you're just an online forum. Why tf would you care about whether my phone is rooted or not?
