I still don't get how so many Bitcoin devs don't have much Bitcoin.
But in a sense, I suppose if they had some Bitcoin to start, they'd be tempted to retire, so maybe there's a selection effect there.

Better to let your enies die in obscurity than to pay them.mind when they lose.

In retrospect, it was obvious the letter they signed was justification to merge a clearly controversial PR. It's not obvious what the second and third order effects will be, but I guarantee this will not play out the way that the signers of the letter think it will.
Happy to eat my words and say that I was wrong if a year from now if there isn't a significant growth (>100%) in large OP_RETURN outputs (>160 bytes).
I challenge any signer of the letter to provide a similar metric to measure whether what they're doing works and under what conditions they'd be willing to admit they were wrong.
