I'm one of those few people who has zero problems with the changes made to Star Wars. I watched a video recently that detailed every one of them, and I generally find them all to be better, at least in their final forms as seen on the Blu-ray or 4K releases (some of the changes in 1997 looked a little rough, though I had no issues with them conceptually).
I do understand though when someone sees things as having gone off the rails. I see it a lot on comic books (i.e. Marvel right now) and while I try not to let it impact my enjoyment of past output, that can be difficult since it is a continuing mythos. Generally though, I don't think Disney is bad with this - even the dreaded straight-to-video- sequels are mostly inconsequential and don't "ruin" anything other than being of questionable quality sometimes. They are easily ignored, though I admit I have a soft spot for some of them and am excited to see a lot of the ones I never have on D+.
