Core owns bitcoin, you can tell this is true because they control who is allowed to modify the code. Core refused to increase the blocksize which caused a massive schism in the bitcoin community which has easy cut the support base for Bitcoin to continue to go up in value by more than half. Core appears to have an agenda to destroy Bitcoin from the inside out.

Assuming core is holding some Bitcoin them self I don't see why they would be interested in sawing off the branch they're sitting on?

They other points you provide may be legit though...
