Because they're generic.  There's a perception that because mechanical keyboards can be so much more than generic, they must be.    
There's nothing wrong with choosing MX Browns or equivalents.  I think some people get caught up in "If you like MX Browns you just haven't experienced real mechanical keyboards." because a lot of people start with some basic switches like Browns, and then when they try Zealios, or U4Ts, or -insert premium tactile here- their reaction is "Oh... this is so much better," and they expect everyone to come to that same conclusion. >
