Yes they are.  Their actions speak for themselves.  They've stalled for years and damaged Bitcoin adoption, use-cases, and marketshare with high fees and slow confirmations.   Segwit as SF just allows them to continue to dole out whatever meager on chain capacity improvements they are willing to grant us.

I reject their economic approach entirely and believe blocksize should always be well beyond market demand.  Let off-chain solutions compete FAIRLY with on-chain, without any constraints.
