Ultimately those are written by lawyers for lawyers. They're extremely long, verbose, and hard for a layman to parse. And that's on purpose. It's a dark pattern to get people to agree because they lack the time to read and to understand [0][1][2].
Reading isn't the same as understanding, and that's a separate bag of worms which comes up all the time in legal affairs. Take the recent Disney fiasco. I don't think the average person would read the ToS and come to the conclusion that Disney can more or less kill your loved ones with impunity in their parks if you watch Disney Plus. Not that other lawyers agree either, but apparently that's the understanding of Disney's lawyers.
Not that pop ups, modals, and warnings are much better. But I think a clear warning/opt out pop up is far better than a link buried in account settings or policy/ToS.

[2] case in point, I'm sure better links exist but I'm sort on time and just plugging what I reviewed from the top of Google results.
