Bjarne Stroustrup, the author of C++ says:

…People reward developers who deliver software that is cheap, buggy, and first. That’s because people want fancy new gadgets now. They don’t want inconvenience, don’t want to learn new ways of interacting with their computers, don’t want delays in delivery, and don’t want to pay extra for quality. And without real changes in user behavior, software suppliers are unlikely to change.

So the quality of software produced by the developer is hurt with the demanding timeline and requirements. Users, eat your own bugs!
