I don't think you even need to go as far as his interpersonal skills. IMHO The fact that the GPLv3 (not the AGPLv3) didn't close the network hole should've been proof enough.

If you care about user freedom, the fact that the GPL isn't viral across the network is such an obvious gaping hole at its center, one that was well known by the late 2000's. Yet through myopia or appeasement, he decided to leave it to the AGPL to solve, and the GPLv3 ended up as a license that still ticked off enough people for them to not upgrade, yet with a gigantic backdoor built-in that allows trivial circumvention of user freedoms.
