I have no qualms with the marketing department at WGT enticing people with new products and encouraging people to dip into their pockets, it's Capitalism to a tee and although some people may not agree with this sort of strategy, it's proven to be successful and has a place in society.
The only way to combat it would be to form a WGT players union and then ballot for a strike!!
My only qualm, however, is when they tweak existing equipment (making it weaker) in order to force people into buying their more expensive products. That's not capitalism, that's just blatant exploitation and will ultimately be overstepped and induce a mass exodus from the site when it reaches breaking point.
