Just like the old days with AOL & their proxies. There are not as many 3G or proxy / VPN users are there are standard users. Therefore, it works - mostly. (Or can work, I have no idea if the particular company / tool under discussion is actually useful.)
Data is data. It can be misinterpreted, but it is still data.
