Choosing a service to NOT selfhost is a subjective descision.

I host 18 Proxmox VMs and 20 Docker containers at home. I also was selfhosting a WebDAV server for synchronizing my Joplin notes between devices and Vaultwarden for managing my Bitwarden vault, but decided to push the Joplin synchronization target to Dropbox [free] and to use Bitwarden's free cloud solution for my passwords and secure notes. I did this because I will need immediate access to these two critical sources of information should my house burn down, or get blown over by a tornado. I have extremely strong passcodes for these and trust the hosts.

This was strictly a personal decision. YMMV.
