Well, its easy enough to go in and remove the matte lines and fix the sabres, you can do it to your own DVD set and reburn it if that is all that worries you about it. Its a starightforward job and would only take a few days of messing about.
Unfortunately, its a lot more than that which causes them to be unwatchable for me.

I could live with a lot of the changes, its the cringeworthy editions that just wreck my enjoment of the movie.
The Jabba scene in ANH is just awful and doesn't work and doesn't help the flow of the film, the comedic CG bits are just awful too, and the ghost replacement at the end of Jedi is ridiculous. I find Bobbas new voice jarring, but that is probably more so for Aussie and Kiwis, it just seems to weird having an instantly recognisable( to us) NZ accent coming from Bobba fett, it would be like the voice of Casey Cason suddenly coming out of C3PO for you American types

If he had released it without the comedy bits, without the new Jabba scenes, the dance numbers, endings and voices, I honestly wouldn't have minded that much. The new CG battle scenes don't bother me *that much* and some of the other stuff just washes past if you are not looking for it.
Its the things that forcefully jar me out of the movie that I hate.
