How would you sell bug fixes? "Hi grincho, how would you like an update for X feature where we fix Y bugs for Z dollars?" Most people would respond by asking why they have to pay more money for things that should be working in the first place. It'll become hard to know whether a developer is fixing new bugs or whether they just wrote some buggy software knowing they'll get more money by selling bug fixes separately rather than writing it correctly in the first place.
Right. I should not have to pay again, or subscribe to some “service” to have the company fix their product’s defects. If I buy a vacuum cleaner that randomly rips up my carpet once every 100 sessions, or a garage door that opens by itself in the middle of the night, I should not have to pay the companies to fix them. This is why we have warranties and product recalls, which are conspicuously absent in the software business.
