As *The Qt Company* we need to adapt our service offerings to the market we want to sell Qt into. We could for instance provide extended lifetime support for old Qt versions, and maintain special long-term-support branches of Qt that continue to build on old OS versions or hardware platforms or whatever for those customers that have deep enough pockets. Perhaps we do that already today (I know, I know, it’s April 1st...). Last year we made a reasonably recent Qt 5 work on a rather ancient Windows XP Embedded setup. It might not have been cheap.

But why should the Qt Project have to care? The Qt Project doesn’t sell into the medical or industrial automation market.

If a medical device manufacturer makes a technology decision and choses Qt based on the policies of Qt "the Open Source” Project, then I’ll trust that they know what they are doing. And if they are not happy with how Qt “the Open Source” Project operates, then I’m sure they’ll check what The Qt Company can provide as a commercial service that fits their needs.

Perhaps that happens frequently already. That would explain the recent development of the Qt Company stock price...


PS: Roland, I was looking at your https://www.theminimumyouneedtoknow.com/agile_book.html page, and judging by this sentence, I think your review process is broken. You should probably ask for your money back from your professional editors, or something… :P
