This has never been a valid argument. Vendors don't get to choose when 
something dies. The customers do.

As the very public conversations with our friend Scott have revealed, 
even Intel is running **in production** systems Qt dropped. Ironic since 
they are using it to make the very chips needed to run Qt at least in 
whole or in part.

There are medical devices still running and being developed with OS/2. 
Actually there are hundreds of thousands of cash station/ATM machines 
around the world still running OS/2 and much of the software is using Qt3.



As of July 31, 2019 One in three businesses still run Windows XP.


As of September 2020 there were more computers running Windows XP that 
windows 8, ChromeOS, and Windows Vista --combined--



As of last month, 1.26% of all laptops and desktop computers worldwide 
were still running on the 19-year-old OS. That’s a greater proportion 
than much younger operating systems Windows 8 (0.57%), ChromeOS (0.42%) 
and Windows Vista (0.12%).


The only thing one has to do to keep these systems "secure" is not 
connect them to the Internet. Most of the manufacturing, medical device, 
metal mill systems are on local loops or hiding behind extremely 
hardened VPNs. One VPN I helped write changes/changed proxy servers 
every 5 minutes using a book code so that no two packets of any 
transmission had the same encryption. It did it all under the hood so 
the video conference software and Web browser had no idea the 
communication was bouncing around the globe and across a few satellites.

Norton sent an email out to customers claiming to drop Windows 7 
support. Suffered a mass exodus of paying customers. Now it has 
Maintenance Mode support all the way back to XP.


It was that or go out of business.
