At least teach them how to not be paralyzed in the cycle of "Maybe I should actually try to vote with my wallet and switch to that iPhone". Switching to an iPhone just makes the issue worse for them, and google is not gonna care. They're probably coming back in a year tops whining in another blog post that it's so different and so much more expensive and less options and that you just want to use google.

Switch to other alternatives, Protonmail maybe, and host your own cloud, even if that's just on a VPS. Backup to different services/medias, and don't rely on specific providers' solutions, so you can switch to an instant, even to local hosting. Even I have the option to instantly rebuild my whole server functionally, and in a few days get the same 50€ CPU and some GPUs. My Backups are in multiple of my locations, on raids, and on google - because we actually get 100 TB for free - and a hetzner storagebox. I don't rely on a single entity, except myself to not forget my password, which I use multiple times per hour.
