So a company, who refuses to port its applications to Linux, is experimenting with UWP for future products. Adobe's Experience Design (XD) CC is going to arrive on Windows later this year, and a representative from Adobe claimed on Twitter that it will use Microsoft's UWP platform. Granted, we're not talking about something like Photoshop or After Effects, but rather a UX mock-up tool, sort-of along the lines of Pencil Project.
It's unclear whether UWP will be a choice.
The logo looks like it's laughing at us with its tongue out.
I still find UWP a concern as Microsoft, while responding to some feedback, still has some key restrictions in play that limit free sharing. Until it becomes technically (or legally) unfeasible for Microsoft to lock down the platform, there will always be the concern that they could, for instance, revoke people's ability to develop software or remove (or prevent installation) of existing software. Even if they don't want to do it themselves, someone with authority over them may just compel it, such as a government who is against encryption.
If you build it, someone will abuse it. The only thing preventing Microsoft from realizing their Windows RT vision, if they still choose to, is the popularity of Win32 applications and how incompatible they are with that framework. We, as a society, want them to remain popular enough that Microsoft cannot afford to abandon it. They want to. They hate the stigma that Windows is where viruses are. That's reasonable, but they're not just throwing out the bathwater.
As an aside: they also want a platform that is less reliant upon x86, and could be recompiled for other hardware if Intel doesn't go where Microsoft wants to be. This is kind-of ironic if you think about it.
