While Phil's reaction may be inappropriate, is Marcus Beer getting a free pass on his behaviour? The degree to which Phil Fish lost his shit and some of the things he posted on Twitter are inexcusable but it's not like what engendered that reaction is any better. Marcus Beer called Phil Fish and Jonathon Blow "poisonous", fucking hipsters (twice), called Phil a total tosspot (twice), a fucking asshole, wankers, called Jonathon Blow's upcoming game "Witless" all because they didn't want to be quoted over Microsoft's new policies on indie game publishing.

Marcus Beer personally attacks both Jonathon Blow and Phil Fish in the first six to seven minutes of this video. Think what you will of Phil Fish but Marcus Beer is the instigator of this.
