Yes, it is true you have suffered at the hands of the big accounts.
I haven't paid that much attention to your case specifically, but once you say you are done, then what do you expect them to do?
Let you keep bad mouthing the platform and still expect to get paid for it?

I know you are in a tough place, but dumping the coin, and then proclaiming it publicly is not how I would have handled it.
I certainly wouldn't make threats about harming the hive.
IF I wanted to continue.
I've been flagged for things I thought inappropriate, and until I have enough stake to change things I just have to conform to the dictates.

If you were getting flagged on original content that is an issue.
Gathering more support is what I'd recommend.
Most people here are fair minded.
