Then what should "they" say? Seriously. it's like the powers that be must account for every fan interpretation of their work and respond accordingly.Then they shouldn’t say that the show takes place ten years before another show that was set in a 1960’s vision of the future.
CBS says its in Prime. For some, that's good enough. or others, its "No way, Jose!" and everything in between. Why not treat it however a person likes, and let CBS say what they want? If it's not prime to someone, it will never be prime.
DISCO will always be Prime to me, sits just fine with ENT to TOS and the like. Yeah, it requires some mental gymnastics at times, but Star Trek has always had that. Always.
