I have no problem with the team sharing strategies with Durant; as others have pointed out, opponents eventually see all that stuff anyway—constant adjusting is a major part of all sports.
But I really like that Jae didn't pull any punches in that interview, which makes me like him even more. We need guys like that.
On a side note, I've often thought that there are so many NBA teams that really don't have hope (thankfully Boston isn't one of them), but if you'd told me a decade ago that Golden State and Cleveland were going to become the NBA's premiere destination teams (even if it lasts only a few years), I'd have called you crazy. So maybe there is some sliver of hope for other sports wastelands like Milwaukee and Orlando?
