At this point I don't really like Core or Knots. I don't want excessive arbitrary data on chain, but I also don't like the doomsday alarmists who think they're gametheory experts at outsmarting states/corpos (who are already buying in to Bitcoin).

If you just think about it rationally for even 10 seconds you’ll come to the conclusion that you can’t stop people from embedding data on-chain, so the best path forward is option that does the least harm, and that’s what Core 30 provides.
I've never found a clear answer as to what fringe edge-case Core 30 fixes by greatly increasing the OP_RETURN filter. Of course, you can't stop people from embedding data on chain. However, I don't think the answer is to make it much much easier to do so (unless there is an explanation that has escaped me).
