> subscription to software that never sees updates nor has infrastructure costs. That’s just a money grab

There is one case I can think of where this makes sense from both the provider and consumer side: niche software that has a high development cost and a small market. In this case, the one-time acquisition cost might be too high for many customers, so moving to a subscription model allows them to use something they couldn't otherwise afford.

Of course, that's not to say that updates shouldn't be expected.
