I certainly understand that it belongs to GitLab and they can absolutely run it in any way they see fit. If there are certain types of content that they do not want to host, they can absolutely refuse to do that -- and remove such content when they discover it.

All I am saying is that they should identify what types of (otherwise legal or permitted) content they will not permit to be hosted on their platform. It is implicit that illegal content will be removed but that's not what I'm referring to.

For example, if a web host doesn't want to host the KKK's web site then they can absolutely refuse to serve them. If $webhost's religious CEO doesn't want to host content related to gambling, well, that is their right. If Amazon doesn't want to host Wikileaks, they don't have to. I just wish companies would state what content they don't permit instead of using a term like "objectionable" or "unacceptable" and interpreting it however they like from day-to-day.

I'll admit that I haven't read all of their various Terms and Policies in their entirety (there's a lot of them!) but I did skim through them and didn't see anything other than the usual mentions.

The reason all countries pass new laws from time to time, including amendments to old laws, is that it is impossible to forsee all possible circumstances in advance.

This is also why there are people whose jobs it is to interpret said laws as they apply to specific circumstances (judges), and they also don't always agree with each other.
