So what? So, you were demanding to know why people were "assuming" Scotty invented transwarp beaming, acting as it they were just pulling it out of their ass when they weren't actually assuming and were taking the word of Spock in ST09, who while not infallible by any means is generally considered to be an authoritative figure.
But -- again -- that requires forgetting the existence of "The Gamesters of Triskelion," "Assignment: Earth," "That Which Survives," "Bloodlines," and "Displaced," at the very least. That is my point. It's not enough to cite the movie alone. The point is that believing the movie requires ignoring
all the other evidence.
Look at it this way. If you've known for decades that you have to turn right at a certain intersection to get to the mall, and someone puts up a sign saying you're supposed to turn left to get there, which are you going to believe -- one recent sign, or decades of prior experience? Yes, there are going to be people who have a kneejerk reaction and believe the sign, and yes, it may be understandable why they want to believe the sign, but
they are still wrong. Defending why people believe something wrong is a pointless effort. Wrongness is not something to defend, it is something to fix.
They're also taking the word of the consensus of editors on Memory Alpha, which also states Scotty invented transwarp beaming.
Then the editors on Alpha are wrong. It's hardly unprecedented. They claimed for years that Victoria Vetri played Isis in "Assignment: Earth," based only on IMDb making that assumption based on a misinterpretation of a fan conjecture whose own originator admitted that he was far from convinced, and then it turned out that she was actually played by April Tatro.
The only "So what?" comes with why your personal opinion should trump an onscreen canon reference?
Don't be insulting. See above -- I'm talking about hard onscreen evidence dating back to the
1960s.
Really, I don't know why you're taking this so personally. All I'm doing is pointing out the objective fact that interstellar transporters have been depicted many times in Trek long before that movie. That shouldn't be controversial, because it is a simple matter of fact.
And as I said, the existence of other interstellar or subspace transporters doesn't preclude Scotty from developing a completely unique version with its own different attributes.
But it doesn't
require it either. "It can't be ruled out" is not proof that something is true. On the contrary -- in order to prove that a hypothesis is correct, you have to rule out
every other possibility. That has not been done in this case. And, again, there are more than 40 years' worth of onscreen canonical proof that Starfleet was familiar with interstellar beaming as early as the TOS era.
