I'm an expensive developer. I love fixing bugs.

I also don't think my job is to be entertained, but to provide value for the company and its users.

Heck, I love fixing bugs and it gives me a certain kind of entertainment.

Making good quality software, or improving poor quality software, is something I enjoy for its own sake. The fact that it also benefits users and my employer is an additional reward.

I don't think it's always developers' call.

Well then they leave and you have no developers to fix the old bugs

I'm sure Apple Incorporated, the most profitable tech company in the world, market cap $1 trillion, can manage to hire a few competent developers that want to fix bugs.

Adding developers to a project by just "buying them" is unfortunately not as easy as you make it sound. (Note: I'm not saying Apple couldn't use more engineers. It's just not something they can throw money at and fix by next week.)
