Software isn’t gym though, it can be “used” by just keeping it in the background for multiple sessions in a tab somewhere, especially if the software does some monitoring so it’s always active.

Whether this makes sense though depends on the software.

For me personally I would not terribly mind to pay Photoshop by the minute because I would need it an hour per year. That’s extra cash that Adobe now just does not see. Most professionals though would still keep paying monthly because they use it a lot.
