I too watched it and thought it was excellent. I think part of the reason Disney cracked down on it was because it made their own star wars works look like the garbage they are. Here comes a real fan (not the current cadre of star wars writers working for disney) and blows them outof the water with vision and creativity.
Cant have competition to the disney 'vision' for star wars, even if its vastly better.

All my vitriol towards TLJ aside I do think Rogue One was a good movie and I was hoping that that was the direction they were going to go with star wars but nope instead we got Rose and holdo :(
