Orrrrr... you just ditch the apps that listen to you (ahem, Facebook, Google assistant, etc) and disable mic access when not needed, and setup your bowsers so they deny cookies or at the very least erase data after closing.
Surfing the web w/ my government PC is kind of humorous, b/c it blocks all of that, except for what it can pick up on the exact immediate session, everything else is deleted. So if I have a tab open shopping for some kind of weird tool and then do a search or FB or other thing w/ ads, it's 100% that exact same thing everywhere b/c there's nothing else to go on. Makes it all very transparent.
I won’t pretend to understand how this stuff works...but for those that do...1) It was Spectrum/cable 2) movie was on for about 15 mins before I saw the ad on FB 3) do robots work after 11pm
When you use that box to get the channel from Spectrum, it sends data back to them telling them what channel you are watching (and probably a history of what you've been doing recently). They sell that data on your history to FB, who then puts the ad into your feed. It's a pretty simple feedback loop.
Unfortunately there are almost no streaming services or any way to get content, besides good old over-the-air TV, where they can't/aren't tracking your viewing for the sake of ad sales.
Oh and yes, the beauty of robots is they don't need a nap.
