Seems especially silly as there’s a real business use case here, for people who made apps using Flex. Not sure how many companies actually still depend on that but it was definitely a thing for a while there. Surely much better to focus on that.
They could as well make use of that underlying x86 emulation technology to run ActiveX components and sell it to those companies that still rely on them in their internal systems — I'm sure there still are such companies.
