Here is what i think is a more balanced view - software devs now have more say/power because they are valuable/rare. More people are working on more complex software, which means a dev background becomes more important to effectively plan/manage it. They are using the power to direct resources to things they care about that were neglected in the past - one of them is surely software quality, because in a "product-driven" company, managers don't care about technical debt and will whip you to work on a shitty codebase regardless of how demotivating it is.
In many cases being more dev-driven has saved time and money for the business in the long run. Even if that didnt happen sometimes, you know what, devs are people too and given the chance to improve their working conditions, they did. I'm personally pretty fucking happy about that.
