Yeah it's a privately owned forum, but it's the main forum for bitcoin, and it would be good for the benefit of all bitcoin users if this forum remained neutral.
I disagree with your view of "main forum" here. It surely is the most used forum, however you aren't creating any arguments for your case actually. If users wanted a more "neutral" environment (whatever this is supposed to mean), they'd simply start using one. That's how these things usually work, nobody is forcing you to stay nor leave.
The fact that this forum is not neutral is very worrying, is this is already a first step in centralizing bitcoin.
No, it's not worrying at all. Besides, this isn't the thread here. You should probably keep this consistent to the thread that you've made in Meta.
This should be about a potential fork (although we drifted away from time to time).
