macOS indeed requires additional effort. But regardless of that customers tend to get annoyed and stop giving you money if you don't ever fix their bug reports.

You fix the bugs in paid updates, and users decide whether the bug fixes are worth the cost.
It's a good balance—if you spend extra time on worthwhile changes, the users need to pay for that time. The users can also decide to stick with what they have if they don't think your changes were worthwhile, which may be a perfectly reasonable path.
That depends. On macOS the churn is high. But there are probably a lot of Windows applications from the nineties that still run unmodified.
