I have a Rivian and it works great with no subscription. The only thing you can add via Sub is a hotspot, which seems reasonable to me.

Essentially the standard is saying that anything attempting to connect to the web must provide an attestation that it's representing a human.
Mozilla opposes it because it's another barrier for new tools to implement, and there is no evidence that bots wouldn't just say 'yeah, I'm a human!'
So no benefit, and more barriers
I think that the issue is that everyone here is saying "everyone should do X", and that just doesn't make sense. Maybe everyone should just pick one thing on the chart and do that to improve the world as a whole? "People will have kids anyway, so that's not a good measure" could easily be reframed as "People will have meat anyway, so that's not a good measure".
We all have a sacrifice we're willing to make to be better, and we don't mind doing. Some people don't want to have kids, so they contribute that way. Some people don't want to eat meat anyway, so they contribute that way. If you want to do better, pick one thing and start doing it, even if it's not perfect.
I agree, I do think they should allow both aa/cp, and wifi while driving so you can tether to your phones wifi. I'm not as doom about secondhand sales as you seem to be though.
