You think I'm overreacting?

Davide Beatrici, known for his work on the instant messaging app Mumble, joined our distribution some time ago. […] In protest, two people left the distribution, including Davide, a friend of the attacker. […] This infuriated Davide so much that, abusing of the administrative privileges he still had, he sabotaged the distribution today in the early morning hours.

Not a good look IMO.
