So, everyone who is perfect, who has never screwed up in their lives, raise your hand.
Folks will joke, but I suspect you'll see few raised hands in the crowd. So, when they screwed up, did all their friends, the people with whom they have supportive relationships over decades, abandon them?
If what they did was bad enough, perhaps. But frequently, the people who have had good relationships in the past will at least wait until they see exactly what you have done before completely writing you off.
WotC created the OGL in the first place. They have made missteps, but then also made good steps. Many, indeed millions, have benefited from WotC's products and actions in the past. So, it should not be surprising that some folks are at the very least wiling to wait until we see what actual license gets released.
I'm all for waiting to see the license or how wotc responds. But I think this analogy doesn't work because your friends are people, part of your social community, and wotc is a corporation, an legal entity that exists to sell you stuff. Granted some fraction of the fanbase may have had personal interactions with some of the designers over the years, but current criticism of wotc is not about those individuals, but about the larger corporate entity. Regardless of what conclusion you come to about buying 1dnd, I think it's healthy to not treat wotc as a friend in a mutually supportive relationship, because it's not that.
