He didn't just remaster, he repeatedly altered the films, even changing the sense of some scenes, perhaps most notably and notoriously the stand-off between Han and Greedo. Most of his revisions have been questionable at best, ham-fisted and cringeworthy at worst.
Count me among the purists who think he ruined his good work ;-)
I think the Jabba scene is arguably worse because it simply repeats the same lines we already had in the Greedo scene for no real gain. It also undermines the dramatic reveal of the much-discussed but never-seen Jabba in ROTJ. Plus the unnecessary fan service of Boba Fett literally turning and staring at the camera at the end.
