I work for a company which sells code and we are a counter example. We make gradual changes in the development stack and processes, every change needs a reason, and even though some changes are necessary, they will not be implemented soon.

Some possible factors are that the company is not that big and we have a feature list to deliver. We are not VC, so we cannot afford to burn money. The devs churn is low, so we don't need to be attractive to many people all at once.

TBH, I don't like it all the time, but it works and our clients are happy with the results.
