What Jessica Price did was much more:
- she insulted a polite fan(and big community figure) by indirectly calling them a "rando asshat"(https://twitter.com/delafina777/status/1014555719352213504)
- she insulted all fans trying to engage with her by saying "Don't expect me to pretend to like you here."(https://twitter.com/Delafina777/status/1014581433937981445). ANet has a culture of positive interaction between fans and devs, and devs share their love of the game with the community. This was pointlessly inflammatory and against ANet's image.
Maybe she didn't actually mean these things. Maybe she was just expressing her frustration, as you said. But her actions say otherwise - she did not apologize, she has only gone on further to attack her (now former) employer, the fanbase in general, to claim victimhood after flinging shit at them. Those are not the actions of someone who was just expressing their frustration - to me, it seems like she really has contempt for GW fans.
Why do you hold Jessica Price to such a low standard? I don't recall Ghostcrawler ever calling fans "asshats", and he had plenty more negative attention, including constant death threats. I don't agree that anyone should be subject to this kind of pressure, but I also don't agree that a dev should be supported when they trash the delicate connection between a company and its customers with careless comments like "Don't expect me to pretend to like you here".
