Let's be fair. Given WotC's track record, the likelihood of them screwing this up is very high. The pessimism is not baseless, by any means.
If they pull it off and D&D 5e is a good game, I'm sure everybody will be happy. History has not given people a lot of reason to be optimistic, though.
I think "completely making things up, and the complaining about the made up thing" is not pessimism. It goes well beyond pessimism. The claim that WOTC will issue completely new rules every single year is a baseless claim. Nothing in the history of WOTC or 5e indicates it to be likely. And it's not right to try and justify that behavior. You want to talk fair - OK, then let's talk fair. Making things up to complain about isn't fair.
