Please include OGL games - otherwise you are furthering WotC's goals.
There are a bunch of companies willing to fight in court Hasbro's interpretation of the OGL, so a game being OGL shouldn't remove it from the list of what people should play besides D&D. We're not anti-OGL, we're anti-WotC trying to pervert the OGL. We explicitly don't want to boycott game systems that use the OGL from other publishers, they are already having enough trouble.
Anyway, being against the OGL is a lot bigger than that. You'd be throwing out the baby with the bathwater - some other Open Gaming Licenses could have the same problem. People were looking sideways at Cypher System Open License because it was based on the OGL and also didn't contain the word irrevocable. (And the OGL was based on GPLv2, which also didn't.) Not that this should be taken as a a sign of wrong-doing - everyone assumed the OGL was a safe harbor for two decades.
So, please include OGL games in what you will play, since otherwise you are following WotC's agenda.
Also just to be clear, what games out there have other licenses are wholy separate from telling people to boycott. If you only boycott when you have a convenient alternative and won't boycott if it means actual sacrifice, that's says something about the person who won't hold their ideals over their leisure.
