Because their fanbase has been brainwashed for years, trust me, there's a lot more corruption with Vince than you'll ever realize. Them treating their female talent like second rate citizens for years is just a start. Yeah everyone knows about them, but a lot know about Impact, and a lot are learning about Shimmer (US), Shine(US), and Stardom in Japan, all 3 all women's promotions (not to mention WAVE, Ice Ribbon, and SeeeDliiing). People that only know WWE need to open their eyes, there's a lot of other far superior products, including the upcoming Wrestle Kingdom 12 from New Japan Pro Wrestling (oh look, another superior product to the WWE).
If you only know and watch WWE, time to open the eyes, see what else is out there, because you know Vince is not giving you what you want, but what he wants. He don't give a damned about the fanbase.
This is the last I'll speak on this, since we seem to be the only 2 that is talking about wrestling, the topic can sink into obscurity after.
