I don’t provide external support to my plugins but they are updated regularly (more than once a month), and use them in my games and apps (including clients). If you find an issue that impacts me and let me know by creating a ticket in GitHub I will fix it. I currently have ironsource for ios/android and mopub for android.
The ones I have removed are the ones either I don’t use anymore or @vlads has released the source code. For those that @vlads has release the source code (admob, appodeal, and others) if you post something in the forums about a missing feature or a problem, I will probably take a look and fix it when i am bored (which happens a lot).
