As someone who've never heard of LVFS or System76, this response seems to be a bit unprofessional to me. He opens and ends with passive-aggressiveness, he points to 2 tweets as if saying "How did you not see these 2 tweets!" Well okay one of them is his reply to the original blog poster's reply to another thread, but a random non-commital tweet after several months of radio silence seems unprofessional too.
