Android System WebView reviews on Playstore
The Android System WebView reviews are basically just a bunch of people who decided to troll Google for putting it on the Play Store like any normal app despite the fact that it's almost necessary (and tends to be pre-installed), considering how many other apps use it; it actually used to just be a part of Android anyway (kinda; that's simplifying it), so that's also part of the reason for the trolling.
Did one person start this trolling and everyone else join in, or did several people do it independently, again encouraging those who came after? We may never honestly know. But it is beautiful and the best thing ever.
