It seems that a lot of folk have wildly different experiences on wild variety of browsers and hardware. I use Mullvad VPN and I think their new DNS blockers seem to eradicate advertisements even on Spotify Free. I also don’t think Google made the adblock rollout global, but did if for whatever subsections of the network. Looks like they’ve backed off for now, even, no doubt a time out to calibrate the evil cheater detecting algos…
Yeah, it seems like it’s intermittent. Like there’s either an arms race going on between uBlock and Youtube system, or else maybe they’re slowly experimenting with the noose to see at what point and with what effectiveness the consumer parts of the equation will start choking up money again.
