The popularity of projects like Unraid, and plenty of similar open source ones makes this comment look silly.
There are countless people running Nextcloud and/or SyncThing on Pi and NAS too. Hell, that there are so many consumer NAS brands tells me that people want to run their own servers.
While there are lots of people that like to selfhost (including myself), the majority of users don't want to. Look at all major services from Google Drive to iCloud to Dropbox. Depending on what it is, I'd even rather pay for a hosted version than deal with it myself. I do this with Bitwarden. I don't want the headache of all the potential that could go wrong when I can just pay $10 a year for a fantastic password manager.
