This would be funny if it wasn't so sad. Bitcoin is the longest chain with the most proof of work. Miners making a change though voting with their hash power is called Nakamoto consensus. It is the way bitoin is changed. It's not an attack it's a feature of bitcoin. People want bigger blocks and on chain scaling. Miners are listening.

Blockstream and core are censoring information to make it seem like an attack. All discussion in support of bigger blocks is being censored on forums controlled by Theymos. He can't sensor here.
