Avoid Tor Browser if you can please, it’s slow and the bandwidth might be better needed by people in difficult circumstances.
A good VPN is better for sharing media.
Well luckily there’s no arguments necessary, as we have the definition by the OSI. I actually rarely see any discussion about that, and when I do it’s mostly ill-informed comment sections.
Open source is not an ambiguous term. FOSS stands for “free and open source software”. It extends the word you claim is ambiguous with the word “free”. That word actually is ambiguous as in other cases it could mean “gratis” and not “it grants it’s users freedom”.
How is that better than the more established term with the very clear definition by the OSI? It’s okay if you mixed these terms up. I just don’t understand what you’re trying to do here.
The source is literally not “open”. It doesn’t make sense to say that without referring to open source.
Saying the source is available to see, that makes sense though.
Something is open source or isn’t. There’s a set, binary definition.
I get the feeling you’re implying a difference/aversion between those two terms which doesn’t exist. This and the combination with a nonsensical statement about amount of GNU packages vs non-GNU packed makes it feel like you’re pushing an agenda here: There’s far more free software than just GNU’s - that’s a success for free software and the GNU project. There’s no connect between the argument you’re obviously implying.
Also HURD never took off - but why should it? The GNU project’s goal is a fully free operating system, with Linux being persuaded to adopt a proper license there’s no real need for HURD. It doesn’t mean it isn’t a fun project.
