I second this, we have had a Synology NAS for over 10 years (i degoogled a long time ago) and have had virtually no problems. I did need to transition to the new “Photos” app which was a bit annoying when we upgraded (after 7 years), but I know that none of our kids baby pics, our wedding pics, our life in general is being scrapped or stored on a server with a terms of service agreement that we basically have no control over.
