Patching or Updates to hurt competition is pretty normal behavior. Blizzard has strangled many a game release this way.
It's one thing for Blizzard to do it to other MMOs.
It's another thing entirely if both games are ultimately derived from the same core franchise. WotC probably wouldn't like that very much, and Larian likely would stay out of Solasta's way as it's being made by a much smaller studio and Larian actually DID contribute to their kickstarter too, so there's that. That, and there's literally no sign of BG3 being fully launched within the next full year (nor should anyone hope for anything sooner), so there's little point to the kneecapping anyway.
Though I imagine WotC would fully encourage something like that for whenever Pathfinder WotR gets released, since it's part of the one property that is in direct competition with DnD. I'm actually 100% expecting a major patch to drop on the same week as WotR's full launch.
