surely, everyone is technically able to cherry-pick and backport bug fixes
into their local Qt versions but not everybody has resources and/or
knowledge to do so.
I personally think this could be an inflection point into forking the Qt 5
"Community Edition", with all binary builds supported and maintained by the
community not affiliated with The Qt Company. There could be a Non-TQC Qt
5.15 Community LTS with backported bug fixes and maybe even new features.
As already mentioned in this thread, the free-to-download binary releases
would be the first thing to appear as soon as the Qt account will be
Of course, there is always Qt Commercial offering but there could be
smaller 3rd party companies offering the same but for less money. It's a
free market but it would a split in the community, and I personally see
this as a bad thing that can happen to the Qt Framework.
