My head canon is that the moment Disney bought the franchise, we entered an alternate timeline. All Disney creations and decisions (like deciding certain existing items are no longer canon) are in the alternate timeline in my eyes!
Just keep your own head canon, fandom is very much like religion in that even amongst those in the same sect there are wildly differing interpretations of whatever weird esoteric shit. Just keep the shit you like, don’t worry about the shit you don’t, don’t be a dick, don’t try to force your interpretation on someone else, and call out anyone who does the previous two.
My personal and not-actually-relevant head canon is that the B-wing was basically a dragster- very fast, but turned for shit, so it could get inside a capital ship’s defenses and drop payload in a minimum amount of time.
(The other thing I do t get about it is why no hyperdrive ring allowing you to retain the composite beam pwnage from the Blade Wing. Maybe slap in some basic thrusters and a dumb droid pilot so it could be dropped and maneuvered while the b-wing did its smash-smash thing.)
Knuckle Dragger: Everything Disney (or someone else) put into canon is good.
Middle: Disney defines canon and it's a mixed bag.
Sage: You decide what is canon and you just put into there what you like.
(e.g. the plans for the Death Star were stolen by the bearded wonder, no matter what Disney or some movie say)
When you have too many cooks in the kitchen, it's okay to hate some things on the menu. Unfortunately, the hired cooks are coming from the same awful school.
