It's not exactly complicated. Either get rid of their tracking cookies (why does a news website need tracking cookies to view an article?), or get consent before they use them.
People don't want to stop tracking their users and so they feign like it's some insanely complex law. It's not complex at all, it's just one that made the thing you used to do illegal, and you need to stop doing it, or get consent before you do it.
If maintaining a persistent session is somehow in the user's interest (say, maintaining an account at a store or online forum or something) then that's a legitimate-business-use exception. If it's for tracking/advertising/etc, then ask for consent, or presumptively don't do it. It's really not complex at all, unless you're being aggressively ignorant about it.
