Oh yeah. It happens.

You may have the threat a bit backwards.

Just try to imagine the spying that goes on over the internet as a 
whole. Governments, ISPs, telcos, businesses, spouses, employees, 
malware on your LAN, bad guys are all sniffing traffic all the time. 
Some digital satellite ISPs have an unencrypted downlink and the entire 
hemisphere can see the traffic.

The difference here is that these security researchers have blessed the 
public with the fruits of their research and we have benefited from it.

It's a gray area. I wouldn't do it myself, but I'm grateful to the 
others who have on occasion done something useful with it.

Yeah, who don't?

It's even a FAQ

Personally, if I were going to transmit a credit card or email password 
in-the-clear over Tor I'd choose Moxie or Jacob over some random node 
any day. But I'd do everything possible to avoid that in the first place.
