Poolin has been mining BSV for weeks now also based on your link.
I'm talking about nodes lol, there's only one implementation for SV, and Coingeek likely controls most of them.
It's easy for Coingeek to point their miners at different pools too
The set of rules is set. That is decentralized. Decentralization refers to the rules. Remember that Craig and Calvin were majority miners keeping BCH alive at one point too
Other BTC miners mocked them for keeping BCH alive while it starved for hashpower
