Unfortunately, Qt's only interest seems to lay in the squeezing of their old existing customers, an ever-dwindling customer base as embedded socs capable of running web browsers become cheaper and more accessible. They _still_ don't seem to be taking the threat of web technologies seriously; Where web tech can now run on desktop, mobile, and servers, QtWeb is still a legal and technical minefield.
They also stopped distributing precompiled versions of Qt publicly, a baffling decision as it hurts their adoption rates even more.
From what I see, the Qt Company behaves as if web technologies don't exist. It'll be interesting to see how this strategy will play out for them.
