Yes, the company I work for now is medium-sized but it is stable and run by engineers so fixing bugs take precedence over shipping a feature by some artificial deadline. At the end of the day our customers and field folks understand that our feature roadmap is an estimate and not a promise. From what I can tell, many of our competitors operate similarly.

But this approach is extremely difficult in some domains. If companies in a particular domain routinely make what you consider to be obvious mistakes there are a couple possibilities. It could certainly be herd mentality and they just need someone to remind them to do more QA and to fix bugs before adding features. But it could also be incentives that resulted in the companies that cut corners outcompeting companies that did things "the right way".
