There are companies that advertise their products doing everything locally. Eufy for one. Although, be warned that anything that sends you a push notification must send SOMETHING to the cloud. People lost their minds a year or two ago when someone pointed out Eufy's push notifications send recognized faces to th cloud as part of their push notifications. Eufy did add a warning and the option to disable, or made it opt in I think.
Anyway, the point of all that is it's all a matter of degrees. Ring and Nest rely heavily on the cloud to process your video and do just about everything. But there are local solutions with varying degrees of local.
Any new shares/reposts would show once the account was followed from the gram.social server. Anything prior to that you would have to view the account on the home instance.
Unfortunately this is going to leave a lot of rural customers in the dark. Poor Internet connection and drm TV. Guess who will control everything they see and hear?
Yes, I'll just build an entire infrastructure to support a gas station lighter that only exists because "if you're dumb enough to buy cigarettes you'll probably buy this gimmick."
My concern isn't money, it's the reliability. If you store those things correctly they will always light. If you store a batter powered device correctly, no matter what it must be recharged even if it hasn't been used. I don't want to have to think about whether I charged my firestarter. The checklist is long enough when you are going camping. It's just one more thing to forget.
Definitely not, just adding information for readers.
