This is just incorrect imo.

Miners are profit seeking so if they don’t wish to mine a sidechain block then they lose out on business by miner who will mine the block.

Drivechain includes blind merge mining.

Also, 75% of miners are required for 6 months to steal btc in a sidechain.

One can make the arguement btc mining is already centralised and by allowing for side chains would help making mining more competitive and decentralised.

There’s also projects like stratum 2 are working on making mining less centralised.
