What do you mean "if Monero fixes everything"? They already fixed everything, which is why the paper shows the decline in their ability to deduce things, and the paper COMPLETELY STOPS showing data after RingCT went into action. Perhaps you should familiarise yourself with the papers that Monero themselves published on this in September 2014, and the follow-up in January 2015? Here- https://lab.getmonero.org/pubs/MRL-0001.pdf https://lab.getmonero.org/pubs/MRL-0001.pdf https://lab.getmonero.org/pubs/MRL-0004.pdf https://lab.getmonero.org/pubs/MRL-0004.pdf Now the recommendations made in that 2nd paper were only instituted in the v2 hard fork in March 2016, because hard forks are hard and it was their first one, but it doesn't change the fact that they published two papers on it to warn the community, made immediate changes so that updated clients used minimum ring sig sizes, and then hard forked to ban mixin 0. Publishing a paper on an already-discovered and already-solved issue two years later isn't particularly interesting or novel.
