The elephant in the room here is the GDPR. None of this is compliant (has never been) and yet is allowed to continue out in the open despite the regulation going into effect almost 4 years ago now.
In fact, an argument could be made that Apple is complicit. Apple has a history of removing/rejecting apps that are used for illegal activities such as copyright infringement or even just breaking some company's ToS. Yet, they do nothing for apps that brazenly breach the GDPR.
Facebook is incorporated in Ireland for tax purposes, as are many other US tech companies. This means that Facebook's GDPR violations are enforced by the Irish DPA. This is a conflict of interest for the Irish government: if they are not hospitable to US tech giants, they may lose their status as a favored tax haven. The Irish DPA has given all indications that it is compromised, and this is a sore point for the regulators in other major EU countries, notably France and Germany.
Just FYI, these are not compliant either, but the same problem above is the reason they're still around.
A compliant cookie banner (or rather consent flow, as the GDPR covers more than just cookies) should not be annoying - it should be as easy to decline as it is to accept and dark patterns aren't allowed.
