"How a Split Happens
Bitcoin’s heaviest-chain rule is what makes this dangerous. If enforcing nodes and sympathetic miners begin rejecting blocks that contain non-compliant transactions, and those ...
That's not how it works though.
The new compliant blocks ALSO have valid proof of work under legacy rules. Meaning new blocks are built ONTOP of those compliant blocks. And those rejected are not built on. Meaning if "valid"(by legacy standards) blocks are being rejected you must not only continue to find non-compliant blocks consecutively, but also no other miner can find a compliant block, or you will be reorged.
I know people think it's two competing chains but it's not. It is one chain and one client is trying to insert invalid blocks (the same as if your client allows double spending). If miners don't capitulate they risk mining a dead chain. (Massive revenue loss).
