Bolded for emphasis. Plushenko received some appropriate PCS that kept him from the gold in Vancouver, the fury never ceased, the sport wasn't progressing blah blah blah, so the only thing to do is make sure it's not possible (or barely possible) to win with quality over quantity. Because that means, apparently, that the sport is moving backwards. Evan did all the Jason Brown things (though not as well as Jason Brown) and won with them, while Plushenko did all his jumps in the first half and posed his way through his programs and happened to have a few quads, and he lost. From there, because of the outcry, it's basically been ensured that higher TES MUST mean higher PCS, in order to make sure the "right person" wins.
In 2015, when the men's competition all shook out, across both programs, Javier made the fewest mistakes. Based on that, he probably deserved to win. But he would've lost to Yuzu (probably) if both had been scored more accurately in PCS. Instead, both received similar PCS, allowing Javi to (correctly) win.
Also, the men's result in 2013, with flawed Patrick winning over Denis, much of which had to do with Patrick's insanely good (and mostly deserved) PCS, placed further emphasis on the technical aspects of skating needing to be somewhat in line with the TES (we don't always see this, but generally, esp at the big competitions, the CLEANEST top guy wins, even if his skating skills aren't as good as the guy below him).
I think that, results-wise, they've got it figured out. There really haven't been many/any major controversies in the results in men's skating since 2013. The problem is how the scoring system is being inaccurately applied in order to reach the correct result.
