When Youtube started showing ads for me I just stopped binge-watching videos on the site, and started using YouTube-dl and watching everything offline.
I added those paywall sites to my hosts file block, I just don't care anymore. I already block everything from Facebook/Instagram, and I'm about to do the same with Twitter. My whole family and friend circle only really use WhatsApp/Telegram anyway, so it doesn't matter.
Those things reduced my screen time a lot and I honestly find it healthy.
