We all make mistakes, particularly when trying to protect something as important as bitcoin. I have been a fan of Matt for a long time.

I like Matt, too. He appears to offer fairly balanced takes on the space, and admitting you were wrong - whether or not that is the case - is a sign of good character.
Pro tip: When Samourai is mewling about one thing or another, it's largely to stir up drama and draw attention
What are you talking about?
Ocean is not including Samourai Whirlpool Tx0 transaction in their blocks.
Samourai encouraged people to believe they were being hostilely targeted by Luke with no evidence. Knots forked away from Bitcoin when the OP_RETURN max was 40 and hasnt changed it since. Knots has always been filtering Samourai whirlpool transactions from its mempool, for a benign technical reason, for years.
Samourai used this as an opportunity to do what they always do on social media: malign people and seek attention.
I don’t know anything about him or anything about what this tweet is about but I rock with that energy. There should be room allowed for folks who receive new information and change their mind.
