By that logic, TOS "broke canon" when it replaced James R. Kirk, lithium crystals, Vulcanians, and UESPA. And TNG did when it gave Worf a new forehead in season 2 and retconned away Data's previously demonstrated abilities to use contractions and feel emotion.
Isn't a lot of that "Early Installment Weirdness" more so then contradicting canon/continuity/whatever that had been fairly consistently maintained between different installments of the franchise? Whenever I hear about ENT being clusterfudge of continuity, it always seems they're claiming it's the latter, not the former.
(For the record, I myself was content to write off "James R. Kirk" as Gary Mitchell making a mistake -- although Peter David's explanation in Q-Squared was the best novel fix, IMHO, even if I'm glad that that was not canon. I guess I somehow imagined lithium crystals doing something different then dilithium, like being the batteries instead of the regulators or whatever the heck the crystals were supposed to do. Later installments did fix UESPA and it's place with Starfleet, so non-issue for me. Vulcanians seemed no different then humans getting called "Earthers" and "Earthmen" in TOS by other aliens. Worf's makeup was always a variation of the same thing, so I put this purely as a productional development outside of canon, esp. since we've had far more drastic makeup changes to characters or alien species before and after. As I recall, Data's lack of contradictions, under his "present day" specs, was established as early as "Datalore" and I honestly don't recall the early episode(s) where he had emotions. Mileage may vary)
Canon is not a vase on a shelf. It's a living, growing entity. It doesn't break, it evolves. And if some part of it does break, it heals, even if it's not quite the same as it was before.
I suppose for everyone, it's different whether the final result "works" for them or not. However, the point I had was actually explained above (e.g I don't get how ENT messed up continuity, given that the "mistakes" are minor at best, and no worse then the inevitable discrepancies the previous shows had).
But there are always some who just cling to their hate forever and refuse to change. Anyone remember James Dixon?
Never heard of him before and did some Googling. Wow. I am equally impressed and shocked by that fan chronology he put together; that's a lot of work to put something together that detailed (I've got an in-progress, non-Star Trek fan chronology on my desktop, so I do have a first-hand idea what's involved). While I wouldn't mix canon and non-canon materials myself, it's still a legitimate premise for a fan chronology.
However, the hate for the Spaceflight Chronology, the official Star Trek Chronology, and the idea of tie-ins not being counted alongside canon is something else, esp. when he makes weird claims that don't hold up (like that the latterwas mostly made of stuff they made up) and his whole belief that fan fiction is just a legitimate, if not more so, then licensed stuff. I don't see a problem with reconstructing the timeline differently from the licensed source (heck, even the Okudas noted in their official one that fans should be free to make their own chronologies with differences in order and whatnot), but the pettiness of it all is shocking.
The guy clearly put a lot of thought into his number-crunching, but I think the hate seeping through it really devalues the whole of the work. It comes across less of a work made by a fan for the artistry or to share what they know, but someone completely jealous of the fact that they're not the ones in charge of the franchise's continuity (or that the franchise moved past the stuff they valued; take your pick).
