Every airline IS different and there's not much point in generalizing. There also seem to be regional or country themes, which kind of makes sense - it's hard for an airline to get away with something much more restrictive if their competitors aren't doing it, unless they are charging much less. What's the point of the pissing match? The only one that matters is the one you're on.
From what I have seen it would appear US carriers are on average more generous in what they allow for carryon than some non-US carriers, but that's obviously not universal. It's also the case that many US based airlines have different rules for domestic flights than international (generally more checked luggage allowed on international flights for free.) It's also the case you can get bitten (or sometimes have it work to your advantage) if a flight is really a codeshare or your itinerary is on a mixture of airlines with different rules. But again, the only one that matters is the one you're on! It's quite possible to be going to or from someplace where all the carriers, or maybe the only carrier, have very restrictive carryon limits. The person you accuse of not doing their research may very well have had no better options, or some other reason they had to take a certain airlines. So unless you're an expert in the ever changing policies of every airline in the world...
