NEVER click decline all. There are loopholes built in that still grant access to “legitimate interest” cookies, which are recognized differently from “consent cookies.” If you click reject all, it still allows collection of certain personal info through cookies labeled legitimate interest. Which is entirely up to advertisers to categorize.
As annoying as it is, always open up options and manually uncheck cookies.
That’s the route I took. I recently bought a 48" 4K monitor, hooked a mini PC up to it, and now I stream my movie and TV show collection through Plex. I still have Internet access on my “TV,” but I’m in control of what pops up (I block all ads on my home network). I just use a small wireless keyboard and mouse instead of a remote.
I haven’t actually owned a TV since about 2008. I have better media options through computers, and the technology just keeps getting better. Cable and public access television are a pain because you’re constantly bombarded with ads. With my own computer, I can circumvent ads and get a solid viewing experience.
