mppt vs pwm

I'm a little curious as to why comparing mppt to pwm often results in being accused of having some "aversion" to watts... what's up with that??? No one is denying mppt takes wattage and turns it into amps at a given voltage. We're just trying to get past the marketing hype, and get to the real facts. If that offends some people, I suggest they take a step back, and ask themselves why they are so emotionally attached to their mppt controllers? I mean, seriously?
