I will never waste my resource in build apps that solely rely on closed commercial entities like facebook, apple. If they choose to ban/block/delete you then all of your hard-work is gone in a second and will leave your users unhappy.
and this can happen to any of us
It doesn't only happen on "closed" platforms.
On facebook and Apple they will just kill your app in a day.
This is why I don't waste any time writing those kind of apps.
