I’m putting this in chat and not in Technology because I’m also wondering about things like clothes, appliances—basically any sort of consumer product, virtual or physical, you can think of that you feel has retained some standard of quality and has not yet been enshittified. I would start by saying that Wikipedia has not yet been enshittified, but perhaps you disagree? Post is inspired by this video.
EDIT: coyotino correctly points out that Wikipedia isn’t a product but a service; poor word choice on my part, just trying to cast a wide a net as possible here in the hopes of making a list of “things that are still good that don’t suck.” Like I said, a wide net 🙂.
As far as the local control goes, you can keep it from phoning home and it will still work. I don’t believe that the Shelly firmware is open source, but they allow you to upload custom firmware that is.
Because you can cut them off from the outside world I don’t believe it is doing the same kind of data collection externally unless you allow it to.
The new “mini” versions of their gear is harder to customize apparently but still possible, they still sell the larger versions though too that are easy to modify.
