Based on what? Obviously the price per second will be higher than a fixed monthly rate. See Lambda vs EC2 pricing for example. AWS’ whole infrastructure is pay-per-use and they’re banking.
Look at the gym industry, which makes its money off people not using their memberships.
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.
Is the amount of work it would take to implement a metered rate at a rate users would pay worth it to capture the people who don't use it as a regular part of their job?
There are other options/build your own but the cost to reintegrate or quality.
