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".
