I don't get the hate against javascript tbh. With this, web components won't work I assume unless the license is known before hand? Or is that considered trivial?
What about wasm? Does it block that? Javascript is at least better than wasm since you can inspect javascript. So people that hate javascript should really hate wasm.
Also, how can the plugin know if the provided source code is correct without compiling it and comparing the outputs?
In a nutshell, Richard Stallman worked in MIT’s AI lab in the 1970s. The lab had a certain ethos that he loved ( https://www.gnu.org/gnu/rms-lisp.html , https://www.gnu.org/philosophy/stallman-kth.en.html ), but when it became common for software to be sold without the source code, he actually decided to start a foundation to recreate that lab ethos ( https://www.gnu.org/gnu/manifesto.en.html ). A lot of programmers agree with his view that refusing to give users source code, and legal permission to use that source code without restriction, is a terrible afront to freedom.
However, people have spent decades telling Stallman that if they adopted his principles, they couldn’t use their computers in the modern world. Every so often, he makes a declaration about various distinctions (it’s okay to use a computer even though the firmware isn’t free; it’s okay to read documents on the web, but any JavaScript should be treated as a program and you should insist on an acceptable license; he, personally doesn’t own a cell phone, but sees no problem with using somebody else’s non-free phone in a case-by-case basis; etc.). This is simply an extension to enforce one of his rules. Some programmers will feel bad about themselves if they don’t live up to Stallman’s expectations.
How can it know when to block a website? Does an human curate a white/black list of valid websites?
I guess what I am really asking is how would it say so? Because even if it is free software I assume this plugin would block it anyway since it don't know.
You could write an html comment just above it but how will I as a website owner know that this plugin:
1. Exists.
2. How to respect it.
There are plenty of plugins but this seems just like a plugin if you like to suffer when you really don't have to. I can kind of understand the goal of the FSF and I do hate some modern software today and companies trying to remove ownership but I have never thought the way FSF is doing stuff is a good way to reach their goal.
