I don't understand that argument. I sometimes use Inkscape but I never have more than a single version deployed on my device. Also, I don't think I'm putting any pressure on the maintainers if I were to insist on never updating from an older version.

Snarkiness aside, being able to "deploy a single version of software" is itself incompatible with the ability to self-host, making it a moot point for FOSS (let alone for FOSS that has no practical reason to be SaaS in the first place).

Sure, but another user might have another version installed. That might be because their package manager is behind the latest release, for example.

Self-hosting means it's still FOSS and you don't need them if you really want to have your own install.

SaaS deployment means it's easier to maintain for the majority who don't care.

Until you have users that want a feature in an older version that's not in a newer one. Oh, and companies are always saying "nobody uses feature X, it was hard to maintain so we got rid of it" which is infuriating if you're a user of feature X.
