Merely expressing disappointment over something here on the boards doesn't tend to bring the other posters out to "defend WotC". When folks just give their opinion that they didn't like or enjoy something that WotC produced, the other posters tend to respond along the lines of "Really? That's too bad. I've enjoyed it."
However... whenever that same expression of disappointment is coupled with the expressed belief that WotC was acting stupidly or maliciously, or doesn't know how to run their own business (usually because the poster feels like they have to use more charged language to really get across how big a deal they think this is)... that's when posters show up to run interference. Someone sarcastically posts something along the lines of "Great job supporting your fanbase by not producing something for Free RPG Day"... and yeah, people will come out and question the poster why they feel that piece of free RPG product was so important to get out there while apparently ignoring all the other free RPG product WotC produces every month in Unearthed Arcana and the like.
Invariably, it comes down to this-- if you post that you aren't getting what you'd like to have, not many people will make a fuss. But if you post that you aren't getting what you'd like to have and it's because WotC doesn't care or are bad at their jobs... that's when you'll see a response.
Now HERE is a constructive thought out response that actually acknowledges what I'm saying. And it's a valid point too!
