Vocabulary used in FCC unlock documentation
3 times in https://modemmanager.org/docs/modemmanager/fcc-unlock/#fcc-unlock-procedures-in-modemmanager--1184 it says that "users [...] complain". I think that's a very bizarre turn of phrase, and not a particularly complimentary one to say the least.
Replacing this with "users [...] reported" would make it a bit more grating to read if I was one of those users.
