Why should I alpha test their bleeding edge versions if any issues I report result in a patch that I myself, and others like me, can't access for at least 12 months? I'd be better off reporting a bug on GitHub to some FOSS fork, because at least when it's fixed I can benefit from it immediately. Likewise any contributions I made would be welcome (Qt Company are now closing patch contributions) They're already doing the work of cherry picking and testing LTS. They're saving themselves a git merge and a git push because they falsely believe this will drive further sales. Maybe it will, but they're still throwing the FOSS community using Qt 5 under the bus. It would have been better to go back to GPL, and had just had timely FOSS releases, since a small business license for the library is only $500/year.
