Take-2 has bullied mods that don’t connect to their servers claiming it’s an illegal derivative work or violates the anti-circumvention clause of the DMCA. If Larian actually wanted to be assholes, they could make life annoying for people who want to make mods.

Again, I don’t think there’s any actual legal merit behind harassment for mods, but lack of merit isn’t always enough for community projects to be comfortable standing up and fighting against well funded harassment.

I do think the lack of merit makes it significantly harder for WOTC to compel Larian into any nonsense like that though.
