The guy actually wanted big bucks from Valve, and valve said no. Its not worth to buy a map, have to rework it and fix it just because some nostalgic Players want it back. Of course he then, after like three years said "Guys you can have tuscan for free lol" after he noticed that Valve wouldn't buy it.
But it still isnt totally worth. Better have some upcoming Mappers get some maps into the game, helps integrate the community, good PR, less work.
