I would guess that Google uses a randomised rollout system to make changes affect a tiny % of users while they test it (common in big software companies). Changing your useragent might make you appear as a different client that’s not affected (yet). Source: I work in software and can guess.

Outer Wilds is not at all nihilistic but it definitely deals with some of the topics you’ve mentioned, so it might not be a good experience for you.

I absolutely adore the game but it can definitely trigger people. I hope you manage to reach a better head space one day so you can play it!

Google doesn’t make money directly from harvesting your data, they make money from harvesting your data then showing you ads based on that data. So if you’re running an ad blocker then they aren’t making money from you (unless you pay them for stuff like subscriptions and apps). As ad blocking becomes more common they are definitely going to get more draconian to try to claw back that money (growth is infinite, profits must go up /s).

Also BTW Google probably makes more like $50 per user per year on average (looking at revenue and internet population) so they would never offer a $2/year ad block unless forced to by regulation.
