The developers, nodes, markets and the media do not have the control of the blockchain.
Only you can determine which is the real blockchain.
Shut up. Miners' own interests are to keep Bitcoin alive, not to choose a scaling system that gives them the most profit. Their interests are subjective and if they choose something which the markets and the nodes don't like, it will collapse.
The markets have the most power of all because they can decide to make miners' earnings worthless if they want to. If miners go and choose BU and no one likes it they'll be mining dust.
IMHO I suggest the following plan:
1. Hold meetings of miners in private (the same interests).
2. You must reach a consensus of a Mining Alliance of +75% to solve this crisis (zero-sum game).
Miners don't all have the same interests or believe the same things about what's in their own interest because they're still people. The fact that you think something so toxic just proves that you support Bitcoin's centralisation (as if a meeting of a few miners would make up 75% of the hash rate).
