Definitely, I can fully understand this in the Stackoverflow situation where they were directly competing with Expertsexchange, but what WePay are doing is taking a business that offer 10 things, emulating 1 part of it and then marketing themselves as the "good" guys.
I mean okay if WePay were an equivalent to Paypal then what they're doing is justifiable, but they're riding off the hate for Paypal to launch their own business and then everyone thinks oh hey they're the good they're a startup, woo startups! They're getting free passes too, Paypal avoided the Wikileaks things because they don't want to deal with an angry US government and suddenly they're the devil for not standing up tro the government, but when WePay do it they're heros?
I can't replace my usage of Paypal (which is just sending money to people and buying things on Etsy etc.) with WePay, for me (a simple user at best) being unable to do that with a supposed "competitor" surely proves it's a worthless comparison.

Sometimes having an arch-enemy is enough for users to understand your value add.
