Google just deleted my nearly 10-year-old free and open-source Android app
One golden rule of businesses (or any investments) is that you should not put your eggs to single basket. With development of mobile apps you just do it, you are totally in mercy of a couple of gatekeepers, like it or not. I would rather focus on recognising and mitigating these risks, and make sure that you do have alternatives. Do not buy into some corporation's promises of not to be evil. They all are. Sorry you had to learn it in hard way, but better late than never.
