Everyone hates Citrea now, though.
I don't think so, I think it was a free advertising. But Bitcoiners usually don't like EVM, so I think if someone will use it, will be people that use ETH, Solana...
We have https://rootstock.io/ that is an EVM Bitcoin Sidechain since a long time, and few people use.
