Wouldn’t say scam but potentially unsustainable. Some years ago I signed up for a brand new startup Nextcloud service which was priced far too low & went under very quickly. Switched to a hosted Nextcloud provider who had been around a long time (still around). They were really good but after a short time I decided to learn how to host it myself.
Hardware wise you don’t need much, I upgraded to a used Pi5 8GB with fanless heatsink case & added an m.2 SSD. Only 1 user on my instance but I often share folders with others, it’s robust & never once crashed.
If exposing to www you need to keep your network secure. There’s a learning curve but self hosting can be rewarding. Any if you’re lucky you might get to spend hours & hours problem solving when something breaks 😉😁
Pi5 8GB with SSD. Only 1 user but often sharing folders with others including Memories photo sharing add on. Syncs between several machines & mobile. Also syncs Joplin notes. Pi5 also hosts variety of other (lightweight) stuff with no issues at all (Portainer, Nginx Proxy Manager, Linkwarden etc).
Previously hosted on Pi4B (4GB) with external hard drive. I’ve found the Pi5 + SSD faster & more robust so for me it’s been a worthwhile upgrade
