Some companies have always been terrible about this. Fan projects involving companies like Nintendo or Take Two Interactive (GTA) are like lawyer bait. Disney has hired lawyers to sue a daycare center that had (clearly unofficial) character art painted on the walls. It's dystopic, but it's the world we live in.

I didn't really expect Funko or 10:10 Games to be like that, but then again I didn't expect anyone would like Funko enough to make a fan page about their dolls.

Other companies allow fans to do pretty much whatever you want with their IP as long as you don't turn it into (too much of) a business. Sega has even hired a fan for their remasters rather than DMCA his project into oblivion.

When companies do this, I interpret this as the company giving a clear message: "don't be a fan of our work or we may apply legal pressure".

After this, everyone will be moving away from this registrar...

Fan anything has always been at the mercy of the trademark owner.
