Replace "Business" with your choice of:
Development Group, Individual, Corporation, LLC, Developers in a Room, Grad
Students, etc.
At some point, supporting "older**" operating systems becomes a detriment to a
project. You spend more time trying to keep the older systems running using
outdated compilers and tools than creating new features or fixing other bugs.
Again, there are reasons to both SUPPORT and NOT to support those systems and
to each developer their reasons are valid. In a utopian world, all the tool
vendors/groups would *always* back port their latest and greatest tools to the
oldest operating systems. But from my 20+ years of experience, this just does
not happen. Tool/Compiler/Library vendors move their tools forward with new
features and drop support for "older" operating systems which brings about the
question that the OP had.
I think your interpretation of a "business" is different than mine? Not sure
what you mean by your #2 statement?
** Older is completely arbitrary at this point.

supporting the older hardware detrimental to their bottom line. 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

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)
