Granted I imagine there's a sizeable percentage of people that watch YouTube from a smart TV and don't have, say, PiHole configured as the default DNS server on their router.
And it's not that I'm against web services making money off of my page views, it's just that some of the ads out there are just downright malicious, and I don't trust advertisement services to properly vet them.
Similarly, most people on Android likely use the youtube app, and not the off-playstore ad-blocking alternatives, or Firefox + ublock.
Though, a technical user may still use PiHole or similar services for their entire home network. Or VPN into their home network for the same protection on their cell service. Though, outside of my personal bubble, this is probably a small percentage of people that go through that effort.
Also I have NO idea what a Pihole is OR a DNS server. My ilk are the vast majority of people online.
