This would be a symptom of bad management, not bad developers. And to add to what others have said, this stereotype never really held up in my experience either. Any serious web dev shop is going to have the framework they use and stick with it for both long- and short-term clients. And there are many mature options here. I don't doubt this happens, a lot, but again, I think it's more about bad management than anything - and bad management will always make bad tech decisions, no matter the topic.
