I thought it was blatantly dishonest: "GPL people should ignore GPL violations because pursuing them will make them look like the giant corporations" is clearly not a defendable argument (although I might be building a strawman here)
I'm not saying we should ignore GPL violations. I'm saying we should consider whether the greater benefit for free software would be in them not being violations in the first place.
Pursuing violations is a very different thing from wanting an extension of copyright. It's very valid to want the former and not the latter.
