EOS does indeed have google services removed, and replaced with microG, which is an open source replacement that allows dependent apps to still work. You can check it out here:

I really like the balance they go for between practicality and privacy. Never tried their own online services so I can’t comment on that part.
As for VPN with hotspot, no idea. :D For what it’s worth, regular hotspotting worked fine in my experience.
If you’re concerned about the lifespan of the device, maybe the FP4 or FP5 would better. Lacking headphone jack aside, they seem like good upgrades and should last waaay longer.
Thank you. It boggles my mind how people seem so oblivious to this problematic phrasing and how unnecessarily divisive it is. I wish these words could be plastered across the internet.
