Those (Invidious and others) are called alternative Frontends, where you really are still using YouTube but with a different Interface, in our case a privacy friendly one.
The code for Invidious is open source and you can run it on your own home server or personal computer. People did this already and there's a ton of Instances that are basically servers running Invidious in different parts of the world.
Using an instance with multiple people helps to mix your data together as it only exists from one end. It's like using a shared library computer.
Using multiple instances (a random one each time) will also mix your data more as request logs are now stored in multiple servers rather than in a single centralized one if they happen to store logs in the first place.
Using a random instance and changing links each time from ex:
is a difficult process and best to be automated. Well, we did that!
LibRedirect's main functionality is to make the use of those instances easier by automating it. It makes life much more easier and privacy more convenient.
Download and install it.
Type or click on any youtube link you want, ex: https://youtube.com/watch?v=dQw4w9WgXcQ.
It will automatically redirect you to a random Invidious instance. You can fine tune your redirections in the settings page.
Same with Twitter, Instagram, Reddit, Imgur, TikTok, Google Translate and much more!
