There are few reasons:
1. Easier marketing: Hiding specification is the main driver that only shows good sides and doesn't show bad ones.
2. To understand detailed specification the consumer must be more or less educated about characteristics and what they realy mean which probably is the problem throughout the whole world. Folks want to be dummy: Give me that thing and get it work right!
I remember things from my country when I was having quite sophisticated for that time Amphiton amplifier that was built by Vladimir Shushurin(who's now Lamm Industries). This piece had plots that covered large work region for different loads, levels and harmonic distortions! Nowdays equipment shows only @1W 20...20Khz.. which certainly sais not even small jota about amp's performance.
Nowday's phrase is "Ear is Your Best Judge"
