I really don't think it's fair to call the post bitter and the OP literally says that they know how hard people work/they don't want to diminish people's achievements.
I think their point was (which in my opinion is a valid one) that getting a VS seems to come far easier to some than others. In no way does that mean that people who have a VS or multiple haven't worked hard to get in that position, but if you spend hours and hours writing applications, prepping for interviews, have worked hard at university, and done everything else that would make you a "good" candidate, I feel it's fair if you get hurt by seeing people say they've secured yet another VS.
I've had one offer this year on my third cycle, and I know the effort that goes into that. I'm not saying you don't deserve success (and I hope everyone on the forum lands their dream offer), but I also do think the OP's post was a justified feeling. Imposter syndrome is very real in this process.
