Y'all never get tired of preaching to the choir, do ya?
Anyone with technical chops has likely tried Linux, or is running it now. 99.954% of the Windows users will either upgrade or roll without updates. Converts are going to be exceedingly rare.
Only way I've got people using Linux was when I fixed "little old lady" computers as a charity thing. I'd throw whatever spare parts I had in there, swap in an SSD, load Linux Lite. I never told them it was Linux. Show them how to get FaceBook and email, done. And I never got a call back!
