Or they treat continuing to use the site as consent. Some of them are really passive-aggressive about it too. I've seen cookie banners with wording like "We use cookies, because duh, who doesn't in 2020? Click here or keep using the site to accept."

Completely at odds with the whole "informed consent" thing.

And then they wonder why we use things like uBlock, which are pretty much the only tools we can rely on to genuinely revoke consent. Or revoke as much of it as possible.
