Do one better: Get control of their internet network access and start straight DNS black-holing whole swaths of misinformation on the internet. Tell them you don't know what's wrong and to complain to the service provider.
You can do this easily with a Pi-Hole under the guise of it being an "ad blocker," and slowly, over time, making more sites unresponsive.
Make a Pi-Hole group for your own devices that doesn't have this blocking, so when they question you, you can show them your device and be like "it works for me."
It's kind of the modern equivalent of using parental controls to block FOX News.
For legal reasons, this is also a joke, because "now that's what I call gaslighting."
Heh, I'll do ya one better, I already replied with this to someone else in the thread, but I'm currently thinking about rerouting their Internet through my network via VPN and pinning my own HTTPS cert to their devices so I can alter Faux News "articles" on the fly with a ChatGPT integration maybe. Wouldn't be able to alter videos, but might be able to slow them down to dialup speeds so they just get frustrated with it and just lean more on the written stuff
I figure this would be more effective than straight blocking
True, but I know them very well so my approach is tailored to them, they generally do read "articles" but will get distracted by those stupid auto-play videos and will start watching a couple of those. If they couldn't for whatever reason I know they'll just go back to whatever article they were reading
