Oh you poor naive soul. If only you knew the egos at play in the top AAA title publishing studios/companies.
People usually only go after devs who themselves have shown contempt towards the WoW community, while making shitty design decisions and sticking by them. Do you see the community go after obscure devs who are not public figures that have not made silly statements in QnAs or interviews? No. They rightfully call out the people in charge who are botching, or who have been botching the game in major ways for almost 7-8 years now, if not more.
End of the day this is still an expensive product you pay for, and demanding some level of professionalism and pragmatism from the people who make said product isn't too far fetched. And if the response to that from the devs is to belittle the game's community by saying "they know better than their players" while having not played their own game for almost a decade, then any angered response (as long as its not extreme) is only natural.
I have personal experience with the senior designers and producers of Anthem and saw how their "know it all" attitude and behavior towards the few people who even played the game saw that game go down the bin. I have been seeing similar attitudes and behaviors from the WoW team for about 4-5 years now, and it has me worried.
