Not all fiction is equivalent. When you are actively world building making explicit revisions is useful for those trying to follow along. If you'd prefer a different word you should say so.
Or that the things that happened in one episode had little impact on the next.
Doctor Who doesn't worry about this.
Versus a new show comes along that is 20% aligned and would need an 80% patch to bring it into alignment.
As an executive trying to revitalize a property where fans are complaining about lack of alignment, do you understand why you might just erase the 20% rather than create 80% more of an otherwise-failed project?
If you're an executive, you understand that the purpose of these properties is to make money. Discovery makes money. It has fans. It sells merchandise. You don't erase money because of the rancor of some pedantic nerds, most people do not care.
Discovery is still canon. The premise of this thread is a conspiracy theory which is not factual. Star Trek Discovery is still a part of the Star Trek franchise. You can still purchase official Discovery memorabilia. You can still stream it. It has an official Blu-ray release.
