TL;DR: This is a common Microsoft business practice.
When Microsoft (MS) management decides to release their next version of Windows, or any other MS software product, it's more or less "Ready or not, here it comes!".
MS marketing, public relations and accounting divisions seem to have more sway than the in-house and contract software developers themselves with regard to appropriate release dates for MS software. Note that the Microsoft brand is more or less an umbrella entity to describe a massive amalgamation of contractors, what some would call a trans-national, Information Technology plantation, under the absolute direction of a core of executives, administrators and architects based primarily in Redmond, WA, USA.
MS PR representatives (many of whom appear to have little or no understanding of software development) euphemistically refer to the cutoff date, the release to manufacturing (RTM) version, the software product image designated as the the initial retail version as "going GOLD".
During the late '90s and early '00s, a rather common statement among systems and network admins as well as developers and product reviewers to describe MS products, particularly MS Windows was the phrase "A shiny pile of poop". Such frank reactions to MS product releases rarely make it to publication anymore.
The reality most of us are now familiar with is that the initial release of any MS software product is nothing more than a public beta full of bugs and errors that we, as paying customers, seem to believe that there is little or no choice but to assist MS in sorting out these issues where our labor, time and inconvenience typically cost MS nothing.
Unfortunately, this ritual has gone on for so long that the general public appear to have become inured to this ridiculous arrangement. Moreover, no sooner and at long last that these MS products have been patched to the point that these can be deemed reliable, MS releases the next corresponding, buggy product version as well as a sunset (aka, end of life, end of support or end of availability) date on the previous, reliable, patched version.
To preserve what has over the last 20 years become the status quo, MS Legal, Marketing and PR divisions (or battalions, squadrons and special ops) appear to have invested a great deal of cash from their sizable war chest toward elevating the reputation of the Microsoft Corporation and its corresponding products at the expense of competitors and reasonable product alternatives, as well as actively interfering in the courts, online and in print (aka trolling) during and after frank discussions of the corporation's actions and its corresponding products.
Presently, the royal "we" has not yet been implemented in the English (US) language dialect or local, although it may be included in a future, mandatory MS upgrade; until then, we the people will continue to refer to the corporation as "it" and its past and present collective actions, to include the past and present individual behavior of Bill Gates, Steve Ballmer, Satya Nadella, et al.
