To put some levity in this rather grim developments, I'll point out that when people on rpg.net and therpgsite generally have the same sentiment about some issue, you indeed know that the End Times Are Nigh!
Yes. Almost no one thinks WoTC are behaving decently or morally. I think on therpgsite you're more likely to see posts along the lines of "Let the (RPG) world burn - a new and better world will arise from the ashes!" - but no one thinks WoTC is in the right, and very few people think this strategy of theirs will ultimately benefit them. Even if they do destroy the 3PP world, they'll be left sitting atop a heap of ruins and in a much worse position than they were before.
