Why not just buy it then? It reminds me of Valve’s treatment of Black Mesa, which made the community love the company even more. It’d be hilariously easy for Blizzard to spend some money on the thing and just buy the devs out, fans love you for it and it builds good will with a fanbase. Corporations can’t see past the legal aspect of things I guess.
In blizzards case, mmo's are a huge time sink and not many have people have time to commit to multiple titles. Acquiring a competitior and maintaining it would see subscribers leave their main offering (which has been optimised for microtransactions and engagement) and splitting the player base.
Valve aren't owned by private equity and other giant corporations so they make good decisions and do things fans like.
A lot of their entire platform is built on mods they've bought and turned into proper 1st class games (cs, dota, Garys mod etc)
I can imagine naked licensing being a factor.
I don't think we needed any more proofs that blizzard is ran by actual assholes, but here be are.
You understand that the people playing Turtle don't pay for it, they don't use the official game because they don't want to pay.
Because they're arrogant, and have critical stakeholders. The fact that someone else took their assets and made a better game runs counter to the story that they're the best in the business.
