I don't think it is at all reasonable to claim that the name of a GPL 2.0 project is off-limits. This license goes back to 2003 and the name is the first word in the license. It is displayed all over the software. The community is full of commercial and open-source tools that include variations of the name. Automattic is betraying the spirit of the license at best, and I would _hope_ flat-out wrong legally to weaponize the name.
