Bitcoin Mechanic is talking in bad faith. At 7:40 he says:

"it's obvious that (people skeptical of the current Knots approach) ... betray an agenda to make Bitcoin more conducive to spammers"

He can't expect to be taken seriously when sharing videos like that, where every opponent "obviously" has a "pro-spam agenda"

(I haven't finished his video yet, but I'm finishing it now)

Some people who advocate for large OP_RETURN limits might be naïve. They might be brainwashed. They might be idiots. But if he says they ALL of them have an evil agenda, then he's not credible

I want a calm, non-paranoid, discussion based on expert understanding of the goals and the trade offs and the game theory
