Windows 10 is in a perpetual state of change due to the evolving situation of computer security.
I would like to believe that, but that isn't just the case. Security updates would not be quite as bad as this fully feature updates that they do. If security was the primary concern we still wouldn't have zero days (or the more troublesome 1 day) concerns that some date back to Win 95 (that's right, there is still code that date back to Win 95 in Win 10), the price for somewhat backward compatibility of legacy programs, I have a program written in 1997 that still works on Win 10 today flawlessly, that's good and bad.).
Also keep in mind that Windows is totally dependent (last time I checked) on the insiders program for QA and some things slip through, even when they are reported. I think there was an instance in this latest release as well of that happening. Win 10 is really not an enterprise OS anymore. Enterprise OSs do not and should not follow a rolling release model (this also include individual software as well).
I am using Windows 10, and also have Corel's latest subscription version. However, I also still have all the versions back to X6 still installed. I fired up X6 and did a brief test drive. Then shut it down. Found no odd behavior. No popup trying to sell me anything. Maybe you just need to adjust your tinfoil hat?
It all depends on the individual computer and workflow as well and how sophisticated your setup is. I've had some programs that were new and people complained about bugginess and my workflow nothing showed up (that's why one should never get the first iteration of any release.
So it wouldn't surprise me if honchos higher up the chain at Vector Capital or KKR were giving orders to Corel's engineers to sabotage older working copies of CorelDRAW as a means of forcing users to upgrade
Well, to be fair, all software vendors have an incentive to force people to upgrade and programs like DRAW are starting to get long in the tooth, so it's going to be harder and harder to do that with feature sets alone, especially if a user(s) can get by with tools that have existed since forever, and I would imagine that is also one of the bigger pushes for subscription as well. With WASM, it would be quite easy to compile that lower level code to get it to run on the web and probably start seeing more programs that way (browser APIs are just about as robust as an OS nowadays). So I wouldn't be surprised if that's the next step and quite honestly, if everything is going the subscription rolling release way, I would prefer it to be solely browser based at that point. Doesn't matter what OS one uses, what arch your on. Shoot, I run a locally compiled SVG editor from the browser and I can run it off my desktop, phone or PI.
And if one starts seeing ARM being pushed (I can argue for and against it, it all depends on the situation, it has it's place), that would also save a lot of time for compiling to ARM if they don't already have a variant ready for that arch (or the manpower/talent to do that).
