It's a subject for discussion, because these days a lot of what Snowden does is prop up his own fame by catching headlines. The line about Facebook being a surveillence company is great headline bait and Snowden knows it.

Snowden's premise is also historically a vague, unsupported claim at best. Ford knew incredible details about its customers and workers, as did Standard Oil. Neither were routinely described as being primarily surveillence companies.

The only thing that has actually changed, is that Facebook can do it easily today, as their users willingly provide the information in a convenient technological manner even after the Snowden revelations.
