Its an interetsing point of view Peter. If it was the case with music then there is no way the music industry would have been as vigorous as they have been in attempting to stamp out limewire, kazaa etc. In fact, that industry claims these sharing sites have cost them billions in revenue. Thats not small bikkies (if you believe them).
I think its very difficult to provide a low cost service within australia given the extraordinarily expensive cost of bandwidth here.
However, re value to sponsors etc because of leech sites I doubt it. the primary reason is because its not measureable. The league cannot say "we had 700 poeple on our official coverage and another 300 who take the coverage illegally... if you get what I mean.
Any league in the financial position of the NBL (a-league, NRL but perhaps not the AFL) cannot afford to have its properties devalued by this sort of activity.
Its a tremendous irony of this forum and TOF, that visitors clamour for coverage, lament the lack of power and strength and reach of the league, and then make comments like LC has in their opening post here, where they hope the league does not clamp down on sites and services that marginalise the possible future strength of the league. Go Figure!
The league is in the opposite of a virtuous circle. It has faced declining coverage and spectatorship since the mid nineties, and therefore has declining revenue and capacity.
I understand that the league's services generally are not great. I hope they can get video streaming up this year - and i hope they or the clubs can make some cash out of it...
... but as a fan, you cannot ask the league to provide this service, as many have here, and then advocate (hope) someone leeches the service which would put in jeopardy the very delivery of the service they want.
