1. If you (general "you") say that you waited 5 years to main BLU (even if you didn't actually know how it would play in FFXIV), it means that: a) you participate on social media, forums, reddit, whatever, b) you really care and are passionate about the subject.
So, if now you come saying that you didn't actually inform yourself about what's being said about your "favourite job" in 5 years, then I absolutly cannot pity you. That's what I meant when I said that people don't "listen". You have people who are actively participating in the vocal part of the community acting surprised even when there was absolutly no reason for them to be. I'm not talking about those who don't participate or check anything. I'm talking about those who do, but somehow "missed" the information about something they really care about and were "waiting 5 years for it".
In short, if you claim to be caring a lot about something, the least you can do is inform yourself about it.
2. Would you question this "70% positive" number if it was "70% negative"? I know quite a bunch of people who wouldn't. Whatever the case, the "BLU debate" was pretty divisive. And while the "negative" side received more support from vocal people (as the vocal side always does), it clearly wasn't enought to push the balance. There has been a lot of other debates in the history of FFXIV that have been way more heated than that. So, if you want to say that the forums and reddit are a good indicator, well, what I'm taking from it is that most people simply don't care. Most BLU threads are already dead, and reddit didn't see a new popular thread about limited jobs or BLU in quite some time now. I do think it's quite plausible to think that most people are in a "as long as it's fun, it's fine" mindset.
3. If you think that nobody did bring the "this is an MMORPG, I don't want solo content!" argument, then I have to question your reading skills. I've argued against countless people using that already. This very thread has a bunch of good examples.

Edit: for Shougun just below... As it's pretty much on the same topic and format.
I think it's fair for him to remind people that they do communicate on this kind of stuff. And that's not the first time he basically said "guys, I told you, but you kept asking for it so...". So, as I said, if someone cares enough, they should make the effort to inform themselves and raise their voice before it's too late. I mean, wouldn't you be a bit angry if you warn people about something for years, and then they act surprised when that thing finally happens and they are like "omg I didn't know!"? Putting aside people who dismiss what he said for... reasons (?).
Regarding the 70% thing, they didn't disclose what kind of audit they did. And I highly doubt that Yoshida himself knows the details. That'd be a question to ask to the community team, as they were the ones tasked with doing that. And if you actually do think that people's voice and feedback were being badly or wrongly reported, feel free to ask them. Probably in a dedicated thread or when they do their Q&A stuff.
As for the disappointment thing, well, it's indeed pretty subjective. And if it wasn't BLU, it would be something else, or impact other people. Anyway, it's now clear that they really didn't intent to implement BLU in FFXIV because of its quirks. No matter if people see that decision as valid or not. It's also hard not to say that BLU wasn't a good candidate for that kind of treatment. And if Limited Jobs are a way to see jobs that otherwise would never come to FFXIV, well, better accepting it and try to get the most out of that instead of staying bitter.
