"Enterprise is their core market"
Quite right, which is why there is one additional round of testing that the article didn't go into - end users. Once the update has been through the Insider program and is considered ready for release, it's important to note that it is only considered ready to release to home/small business users. Enterprises on the Current Branch for Business (as it used to be known) get the updates a bit later once the update has been unleashed on home users and any final major bugs have been called out and patched.
Hence, these testing issues aren't a major concern for enterprise - they know that they'll only get the update once millions of other people have received it without major issue. It is however a big problem for home and small business users that are now being treated as a final round of testers for enterprise. It also means that instead of these bugs being caught and quietly patched during internal testing, they're now showing up on end-user systems and are causing much more noise and stink.
Ultimately, I fully agree with the article. MS's development approach to Windows 10 is broken and changes need to be made if end users are to see Windows 10 as anything other than constantly flaky and beta software.
