I see where you're coming from but you have to look at this logically. If things worked the way you wanted them to than an evangelist would just have to retire if his company fired him. I've always though of Evangelists as slightly more useful sales man. Because they're trying to sell you something just like a salesman but they can also provide useful info on occasion. But they're still salesman and that means they'll talk up whatever company is paying their check.
