Shitcoiners will shitcoin.
If you create a Drivechain to attract shitcoiners to Bitcoin, you are hurting Bitcoin.
If you wanna increase OP_RETURN limit so non-monetary projects can run on Bitcoin, guess what? Shitcoiners will still shitcoin.
Let shitcoiners make their own chains and go to zero, instead of making Bitcoin a shitcoin.
