The criticisms don’t seem valid, though. Projects have to function within the law, and pretty much any popular project has to address these legal issues. Here’s the Linux page about its trademark, for example: https://www.linuxfoundation.org/legal/the-linux-mark

> The Linux Foundation protects the public and Linux users from unauthorized and confusing uses of the trademark and authorizes proper uses of the mark through an accessible sublicensing program.
