Its much worse in other scenes.

D&B is full of people dragging there mates round a tired, predictable circuit of talentless hacks with boxes of dubplates.
Shame really, because some of the music is fantastic, innovative stuff. But the scene in the UK sucks.

Techno is probably guilty of "helping out your mates", maybe just because its human to want to put you and yours above a bunch of strangers. Too few people are professional and objective when it comes to music.
