When you hover and see the link target at the bottom that means the HTML link target is as desired, but on link interaction the website uses a JavaScript event handler to prevent default behavior (browser link navigation) and instead redirects you to their tracking.

Blocking their javascript scripts may prevent the event handler injection.

Alternatively, as a fallback, if you see the link at the bottom, copying the link via context menu should work. Depending on your browser and their implementation they may inject and replace the copy to clipboard too.

To anwer the title question:

By not using these services. They manipulate links you give them. They can do whatever they want.

Haha btw Fedilab does the same with Youtube, but using random Invidious instances. Thanks Fedilab.

There's an extension for Firefox and maybe Chrome that should help. I think it's called ClearURL, or something similar. It removes the trackers from the ends of URLs

EDIT: That's assuming that it's a legitimate tracking URL, and not something that's been added by malware.

Firefox can do it without an extension now

As Android App, you can use leon url cleaner which removes them if possible
