I'd also add "there are almost no developers using it on the job market" to the list why some technologies are no longer fit for purpose. It's a major one.
Sort of tied to the ecosystem (no devs - not many things get mantained/created).
I do think that holds more water than just "It's old".
However for pretty much any dev I would hire for a job they can get to grips with a technology that's older pretty quickly. Where it does get dicey is when good dev just refuses to work with it. For those devs, I think, when they hold that opinion it typically means one of those other reasons is behind their refusal.
