That's a terrible take, and quite untrue. 

Vitor solved Repl y Guy spam in the client after he realised the main relays weren't moving quickly enough.

IDK about Alex and Will since I don't use their software, but I see no reason to believe they didn't care.

What does concern me, and that Repl y Guy has made obvious, is that the public relay operators are both a fragile point of centralisation, and too rigidly ideological to solve any unwanted content problem without the threat of arrest to back it up.

Why the client devs are drawing heat IDK, they have no more control over relays they don't operate than we do.
