In general, Google is right and there is almost nowhere to get away from this rightness. After all, if you judge, now the company does not already receive income from Netflix, Spotify, and other services that make big money on subscriptions, but at the same time do not want to share these earnings with the search giant. Therefore, it is logical that Google decided to simply take and expel developers, putting forward impossible demands on them. It is clear that no one will agree to deduct 30% of their income to her, and if so, they will not use the privileges of Google Play.
