For my business, I drew the line at 2 major releases behind Apple which aligns well with Qt. I service higher education and govt labs where people stay with hardware as long as possible for personal or corporate IT reasons. I weighed servicing those few clients with NOT having access to things like newer C++11 & C++14 because I had to support those older compilers and for my business that just didn't make sense. We _want_ to use the newer enhancements to C++ to make our developing lives easier and create more solid and stable code that the newer C++ and tooling brings. I communicate well in advanced our plans so that it isn't a "secret" to anyone. I recognize that _your_ business may have different needs and reasons than mine. There is no "correct" answer in this discussion. I just need a clear road map from Qt about what versions of Qt will support

Total Cost $150 for the Windows 10 Pro license. Linux would have worked also. Those "cheese grader" MacPro machines just keep going. Nothing wrong with them.

You seem to ignore facts that
1) many people don't use Qt for business reasons but have completely different motivation
2) Qt Project itself is not a business project

But, as Thiago said, there is no need to vote (because Qt Project is not a democracy either)
