What's the point in singling out sports entertainment?

Apple cleared $100bb predominately selling consumer electronics, should everyone who bought an iPad feel bad for not donating that $600 to cancer research?

Facebook just threw a billion around on a photo sharing company.

Microsoft just threw a billion so it could acquire some more patent ammunition.

Everyday billions and billions of dollars are thrown around to buy all sorts of things, who gets to decide what spending is "right" and what's "wrong?"
