Very unprofessional attitude from Nack. Yet another Adobe employee that looses his temper publicly. The atmosphere must be rather tense at Adobe HQ.
I think it's a general air of incivility. The OP feels that she/he has a right to insult other people without being bound to any rules of decorum, let alone grammar or sentence composition, just because he/she is a customer (presumably a
paying customer) of Adobe's.
The blogger's response (even in the edited form -- it looks like it was modified since it was posted above) was rude, too. I don't say being rude in response to being rude is the right thing to do.
But I do have to say, that I not-infrequently on Twitter receive semi-nastygrams back from people in various agencies or software development companies if I say something about their product. I've received messages back from the local bus service many times, when I (politely, and in line with my duty as a resident and citizen) criticize them for what I see as a failure in their mission to provide high quality public transit services, or when one of the Public Radio apps incomprehensibly updated in such a way that it had to be downloaded separately from the App Store and the old version manually deleted. In these cases, the messages back weren't nasty, but rather clueless (their refutations showed they didn't understand what I was criticizing to begin with). But then, I also wasn't rude to
them.
The blogging atmosphere and the feeling these talkback reply sections of web pages give people that they have some magical right to make unnecessary comments are certainly also to blame, but no one went out and invited the OP to be rude.
I think people should focus on their own ability to be
civil to others. When the OP receives incivility for reasonably polite behavior, then she/he can come back and post, as far as I'm concerned.
