There is no one who needs their brand of "saving", there are no crusades to win other than imagined ones, and their hate makes them a loser by default.
There are certainly plenty of issues with both asics related to manufacturing and delivery. But nothing they say or do is going to affect it one way or the other, nor will it likely affect anyone else's choices. They are powerless, and at some level they know this, and that only fuels their hate. Being irrelevant really pisses some people off, and makes them even louder.
I wish I could reach out to each and every one of them and cure them. Unfortunately, I think only the passage of time can do that. Eventually every vendor will either deliver or go belly up. Then what will they have left?
The obvious counter-example to your claims is the PSA:
If you have ordered from ButterFly Labs and have not yet received your product, you are entitled to a refund whenever you request one (per FTC rules).
First ask ButterFly Labs for a refund, they will probably say no but you might get lucky.
If you ordered via PayPal you can file a complaint with them even if you are outside the 45 day window. Multiple customers have already gotten a refund from PayPal that was outside the 45 days.
If you ordered via Bitcoin or Bank wire, you can fill out a complaint with the FTC at http://www.ftc.gov/complaint and they will advocate for you with ButterFly Labs to get your refund. You can also contact the office of the Kansas Attorney General and inform them that you have had your money taken with no product delivered for months, just more promises.
You can also do a paper filing with the DA here: http://da.jocogov.org/complaint-forms
There are also several threads on how to get a refund from ButterFly Labs, here are two:

https://bitcointalksearch.org/topic/butterfly-labs-did-everything-they-could-to-make-getting-a-refund-impossible-272585
This message has grown over time and helped a few people get refunds from BFL (who at first refused to provide them). Customers are entitled to a refund until they are shipped a product (thus creating a 'sale'), many were unaware of this. This is real.
Maybe you were not around earlier (it would explain a lot) but the "vendor haters" were in the minority before April. There was a lot of euphoria going around and back then "the 90%" had a different take on things.
There is irony here as well. It is your post that is actually an example of the bad behavior. It contains only disdain and insults for those that disagree with you. Other people can speculate as to why you are so bitter in other threads.
