Interesting detail: note how it does not mention or even try to explain what would be allegedly violating the families program eligibility. This is likely part of Google’s procedures to tire the devs down.
If the dev is smart they should be capitalising on that nice, nice Streisand effect. “Google uses its monopoly over app store to remove competitor Organic Maps”. Remember - against Google you don’t need to pull your punches, you can go all out.
I also hope that the dev uses the opportunity to advertise F-Droid. BTW I’m installing this right now.
