can bitmain close my wallet?
can bitmain charge me to open a btc wallet in future?
can bitmain exclude countries from using the network?
NO,NO,NO
The whole concept of btc is built from miners, they get rewards for their work...wtf are blockstream doing to get a slice aswell?
your missing the point, apart from the tech on both coins...im more concerned with blockstream owning the whole crypto ecosystem, something your either ignoring or dont understand.
Can Bitmain refuse to verify my transactions?
Can Bitmain take steps to charge me outrageous fees?
Can Bitmain use a backdoor in my miner to get me to stop mining?
Yes,Yes, Yes
You are so focused on Blockstream that you are willing to follow Bitmain along in their plans to do a total takeover, of both chains. I guess manufacturing and selling 70% of the Asics and running several pools that have a lion's share of the Hashrate isn't good enough. Now he can control two coins, and pit them against each other so that he can profit even more.
