I don't believe this is what most people on this thread are doing.
There's a difference between advocating for better communications efforts on the part of a company, and asking for ourselves as individuals to be listened to. If I were to write something along the lines of "SE needs to implement X so that I can do Y, and if they don't I'm going to quit", that's a Grade A example of entitlement. But I'm hard-pressed to recall such examples in this thread, or indeed on many of the feedback threads about Eureka (or Diadem 2.0, or Diadem 1.0, or any other piece of content). In fact, posters often take great pains to speak on behalf of entire portions of the user base, explaining why things aren't working well. That's feedback, not entitlement.
To be sure, there are the entitled trolls out there who are just venting. But I think it's somewhat disingenuous to come into a thread that is clearly focused on a communal (not individual) request for feedback, and throw out a term that doesn't really apply. Your comment would fit perfectly in a number of self-important threads floating around the forum. Why were you picking on this one?
Secondly, yes, your implication that younger generations are more entitled did cause offense and set people off, deservedly so. Entitled people have always existed, will always exist, and their numbers, I'd argue, are fairly steady throughout human history. It's not a generational thing. What is generational, however, is the size of the megaphone that entitled individuals can use. Up until about 20, 25 years ago, people who were entitled could communicate about as far as the sound of their voice traveled. So, they sat around bars and bitched with their friends - an activity many of us are very familiar with. Then the internet came along, and their entitlement was visible to thousands of people, at least. But that doesn't mean people are more or less entitled - just that it's harder to ignore them.
