For some reason, every time an award or a nomination is announced, everyone tends to focus on who was "snubbed". Why not just celebrate for the people who were lucky enough to get nominated? Just a though. Remember, whatever the snub is, it's not as bad as the Frozen casting.
But really, I think everyone has some hopefuls in mind that don't end up being nominated, and people like to voice their opinions. Some are just more outspoken than others.

Also, the population of people who are actually knowledgeable about the grand-scale landscape of any Broadway season is very, very small. The majority of people whose interests in the Tonys are piqued are usually personally invested in/a big fan of one or a couple of shows. When the shows they get personally and emotionally attached to don't get a nomination, they call it being snubbed or robbed because they simply don't have a big-picture idea of what other works in the season have been. I realize this sounds like a disgustingly snobby answer, but I think it's reality.
I think it's just human nature to put a focus on the "snubs"...it's done, to your point, with all of the awards shows. So as long as the focus on the "snubs" is not the sole focus, I think it's OK. There's been a lot of praise heaped on the nominees by this board today as well.
For me I'm just disappointed. I don't feel like American Psycho was snubbed. It did get two very worthy nominations after all but I was hoping Benjamin Walker and the score would be recognized. It almost seems pointless though since Hamilton will win everything. I can't figure out if that's positivity or negativity. I like Hamilton so I guess it's a positive focus.
