He changed params for no apparent or obvious reason and broke a lot of mods. That doesn't sound very mod friendly to me.
And even if he did that? From what I saw, he always mentions which parameters he may have changed on the modding side of things (referring to updates' change logs). Again, it's not his job to maintain the mods operational in every update, that task is solely up to those who created the mods.
To me it sounds like very simple and basic stuff. You create a mod for a game? It's up to you to maintain it, not the original developer.
