art is dead
This is amazing. the next thing they'll want is revenue from drinks sold, etc. These are the same morons who put standards on reselling old CDs so high that reasonable prices can't be levied in response to minor scratches that don't affect performance.
That aside, free market is free market. If you want to turn "art" into an industry, music into a "service" and performance into a for-profit seminar, then "what's good for goose..." people are just taking after the same business model: making money off of something they only have secondhand contact with. No business criminal at the RIAA or the british equivalent has any right to get all high and mighty regarding the "ethics" of regulating "art for profit."
