What does that have to do with software engineers? I highly doubt any of the software engineers just up and decided to remove the feature one day on a whim. Someone outside of software engineering likely came up with the idea. Do you expect people to quit over removing drag and drop on the task bar?
At this point? Yes. They should care enough about computing to take a stand against dragging it backwards. But hell, they won't quit over knowingly and actively making everyone's lives worse and handing tracking information over to oppressive regimes, so I clearly expect too much from them.
