like the line goes "you can have your own opinions, but not your own facts"
you can of course, leave out what is canon in any show or movie 'universe', but because you wish it to be so does not make your view "true" except in your mind only
it is those who own the rights to these things who are in control, simple, basic,fact
Its a basic LEGAL fact. The actual control is in the hands of the consumers, not the owners of the rights to the product. This is true of ALL products. Most major changes to products do not impact the producers of the product in any significant way. But then other changes sometimes creates such a backlash that the very existence of the product is put in danger. I have many examples for this, and even for Star Wars we see it in the Solo movie. What I find amusing is the willingness of so many Star Wars fans to blindly swallow whatever their handlers tell them to (post Prequels era). I am specifically referring to Disney Star Wars, not the OT or the Prequel movies. They are being ordered to swallow Rey, Finn, Poe, all the SJW politics now in the SW movies, space fairy Leia Poppins, hyperspace tracking and hyperspace slice and dice, all sorts of heavy handed stomping on the SW universe...and they are okay with it.
You are willing to even
defend it. This dynamic is identical to Apple fanboys.
Look at the Star Trek fandom. Make heavy handed changes and try and shove nonsense down our throats, and we throw it up and turn our backs on it. They own the rights, so what? Without the fandom, movies bomb, merchandise sits on shelves, and pretty much 100% of the time, changes will be made according to the wishes of the fandom because without them there is no profitable Star Trek. Kurtzman pushes back, but CBS appears to have benched him for Season 3
because of Season 1 and 2 being rejected by Star Trek fans. We saw the addition of hair, the turning up of the lights, and the adding of humor in Season 2
because the fans wanted it. I think Season 3 will be just as bad or worse than Seasons 1 and 2, and CBS will make more changes until they are able to leverage the massive international Star Trek base. That means doing the Star Trek the fans want.
I know Star Wars fans who do not see things the way you do. They love some of the games, and hate others. They can articulate what they like and don't like about the new movies beyond just saying things are canon because the showrunners say so. They are
picky about their Star Wars stuff. That is a good trait to have when choosing products of any type.
