> RED Cameras are good and widely used, iirc - probably worth giving them the benefit of the doubt as they’ll not want to damage their reputation and profits by abusing their T&Cs.

This is an appeal to authority, a logical fallacy. That particular niche of users has likely never brought it up to people attention. EULA are rarely brought up at all, and when they are its just in some software within tech circles because tech sector enthusiasts like to review. It doesn't matter that high powered hollywood execs and prosumer gearheads have used it and ignored it. It is very valid to assume it simply never has been challenged.

The question "is it legal" not "will it hurt me" not "will it hurt them".
