The trademarks owned by the Linux Foundation are listed here: www.linuxfoundation.org/legal/trademarks Neither “systemd” or “segmentation fault” are listed. Something smells funky here.

Can a third party lodge a complaint and claim to be acting on behalf of the Linux Foundation? Maybe someone is trolling here.

Isn’t that what copyright/patent trolls are? People who lodge complaints on the behalf of others, regardless of whether or not the original owner of the intellectual property actually cares. If it’s the original owner, then it’s usually just considered to be protecting property.

No, patent trolling is when you patent a bunch of stuff and make money by suing people instead of actually producing that product.

Filing complaints on behalf of someone you don’t legally represent is fraud.

Well damn, I guess fraud must be a lot more widespread than I thought. Because no one seems to get punished for this behavior. Just recently, Lockpick, a tool for getting Nintendo Switch roms off a physical device, was dmca’d, and the person who filed the complaint admitted to doing so on twitter. They received no punishment.
