LibRedirect is pretty great. Everything from reddiot, fandom, youtube, imgur, google maps... (it's a long list)

has open source or alternatives that you get sent to instead of the big corpo tracking site. I love the fandom, reddit, and youtube redirects, because so many times I end up being linked to those. You can also turn off the redirect per site if you want, so if an invidious link (for example) just refuses to load, you can let youtube track you and see the video.
