This assumes the only source these companies collect from is your internet traffic. It’s not.
And even if it was, VPNs don’t protect against fingerprinting.
For the past few months I’ve been using kanary which is a service that searches for your information on hundreds of different data mining sources and submits deletion requests for you.
I started with ~225 exposures and it’s gone down over time but I’m still sitting at ~50 exposures and it seems to have plateaued.
This information was data like who I’d married and when, past and current addresses, family members, etc. None of which was gleaned from internet traffic.
The way I solved this was to leave my regular browser setup alone, make a new Firefox profile just for YouTube, install ONLY ublock origin, and create a shortcut to that profile on my desktop.
Now I only use that profile for YouTube. I haven’t seen one ad since this thing started.
The vast majority of the Android/iOS flamewar is pro Android on fedi (mostly Mastodon for me). I usually don’t bother but I thought my comment was at least sort of funny? oh well.
