It's certainly cheaper to have a couple of sysadmins, but then again, it depends on how valuable is the stuff you're dealing with. Small web agency? Probably not. Supporting dozens of journalists (like my org)? Absolutely.

There are also trade-offs. A few sysadmins can't host emails against hostile (sometimes state-sponsored) parties like Google can. We can't roll out a better messaging service than Signal. We could roll out our own VPN, but if the goal is getting lost in the noise, you want a popular VPN, not routing journalists' traffic through unique IPs.

On the other hand, just Nextcloud and GitLab (two fairly common services) require about 10h/month if you don't want to be major versions behind or miss security patches in minor versions.
