That opinion happens to be supported by large scale social experiments such as facebook. Time and time again, important aspects, such as privacy, were worsened, but their users stayed. People (as a whole) are lethargic, not masochistic. To make things worse, Linux isn't for the desktop. You would first have to convince people that they really don't need all that Windows software, and then make Linux PCs (with a super user-friendly distro) a commodity. In the mean time, people are ditching desktop over mobile/tablet, and there is a lot of "niche" Windows/macOS software that isn't available for Linux. It just isn't gonna happen.
