Although now that you mention it, that’s not always true… which is exactly why the AGPL was written.

I think it’s silly that some people insist that FOSS licenses are perfectly infallible and proprietary licenses are always fatally flawed.
They all have pros and cons, people misuse them, and none of them are perfect. If there was one that was perfect, everyone would use it. But everyone has different needs and concerns. Pick the license that does what you want to do.
That's why GPL has an 'or later' clause, to patch fix issues when people find out ways to remove the four freedoms while complying with the letter of the license.
So I'm specifically not making the argument that "FOSS licenses are perfectly infallible", only that everything proprietary licenses do, FOSS licenses and support contracts do better from the user's perspective.
