Very handwavy most of these stories seem to revolve around Google tying ad accounts and play store accounts, and having a VERY EXTREMELY heavy hand on ad accounts, which results in the banhammer smashing distantly related play store accounts.

The safest way to handle this is probably to not use both google play store and google ads. Going to be pretty hard to make an app without Play Store so I guess that means no using Google Ads. Too dangerous and Google will not support.

If you used, say, Facebook "audience network" ads, then no matter how angry Facebook gets, regardless if they're correct or not, at least your app would remain up.

Also if you're launching a startup you're probably not making much from ads and as using google ads is a HUGE existential risk for any app developer, you'd best not use ads. Its not like any end user ever used a startup's app because they like how well they implemented the ads.
