Okay, lots of folks here seem to be making all kinds of wild speculations on the basis of essentially no meaningful information. (Except for
@Maurice... thanks for being a voice of reason, dude.) I can believe that some executive producer at some point for some reason told Eaves and his team "make it look different, but recognizable." Beyond that, though, this is all smoke and no fire.
I've already posted at length about this on the "Enterprise on Discovery" thread, and I'm not going to try to repeat all of that here (especially inasmuch as many of you have probably already read it). Long story short is this: what Eaves is quoted here as saying (in the now-vanished FB thread) about the reasons for these changes (and for that matter the design changes in ST09) simply doesn't make a lick of sense. It doesn't dovetail with any understanding of how intellectual property law actually works (in general), nor how major entertainment corporations (in particular) actually manage their IP.
In particular, the "25% rule" as described is not an actual legal principle, nor ever was... nor ever
could be, because it doesn't make any sense on its face, as there's no consensus way to quantify the elements of a visual design.
More importantly, the rights to the original
Enterprise (and any other ships, designs, characters, or concepts) from TOS have not been divided up for inscrutable reasons amongst unknown parties. Lest there be any doubt about this, consider the
legal boilerplate that CBS requires fan filmmakers to acknowledge, which reads in relevant part:
"Star Trek and all related marks, logos and characters are solely owned by CBS Studios Inc." That is as crystal clear as it's possible to be.
Paramount Pictures holds the film rights to Trek, including the existing film library and the right to make new ones, as a matter of contract under the terms of the 2005 Viacom split. Make no mistake, however, film rights do not confer ownership of the underlying IP; those are two
very different things. CBS owns everything (i.e., all the IP), and retains the TV rights, meaning it can use that IP on TV as it sees fit (whether streaming old shows on Amazon Prime, or using it in new productions like DSC, or anything else).
The only really sensible and credible statement I've seen from the thread was this one, from Scott Schneider:
Honestly I really know nothing of copyright law. I only know what we are told. ... If Ive learned nothing else in 30 years is that studio politics, contracts and legal issues are not black and white. Something that should seem simple often is over complicated simply because one person wants it that way. Never underestimate the power of greed and control.
Note that two of the three things he mentions have bupkus to do with anything mandated by law, and as for the one that does he acknowledges complete ignorance.
As the old saying goes (often misattributed to Mark Twain), "It ain't what you don't know that gets you into trouble; it's what you know for sure that just ain't so."
