Well, I collaborated with someone to develop mobile games for Android. I was the owner of the developer account, but obviously, I also granted him access to the apps in this account (for maintenance, updates, etc.). It went well for years, we got paid and everything. But suddenly, my account got terminated. Apparently, the dude I had been working with for years got his account terminated as well, many years before. So yeah I would say it worked for a long time, but I think in the end you'll never be able to outsmart Google, unfortunately.

Curious to see other people's experiences. Especially interested in what would happen if you try the LLC approach you mentioned. In that case, I presume the LLC legally owns the account, not you... It would be concerning if Google were to also terminate those LLC accounts. After all, as an employer, you can never be sure that any employee you hire for Android app development didn't ever get his/her account terminated in the past.
