I got myself a synology about 8 years ago for the same reasons you listed up. NAS storage local and out, while being able to run a few small services like Plex for streaming media (looking to try Jellyfin at some point).
There is a premium cost for the NAS but att I didn’t want to fiddle around building my own and then setting up something like Unraid, which atm is running on and old laptop and might be my pick for my NAS solution in a few years.
You made the mistake of commenting positively on a product you like on an lemmy post about that product. People on lemmy post only about companies to hate on them, much of the time without reading, thinking or knowing anything about it. And yes everyone who don’t jump on the bandwagon is downvoted.
Apple and Tesla seems to be the main targets, yet no valid alternatives or constructive discussions are ever to be had.
