I remember when Assange founded Wikipedia, it was one of the reasons I thought.
Yeah, but keep in mind there was growing awareness of mass surveillance in the years leading up to the Snowden revelations:

Similar to how the show 24 manufactured consent for torture, imperialism, etc post-9/11, part of me wonders how much of a role POI played in doing the same for mass surveillance.
Enemy of the State came out in 1998, Sneakers came out in 1992, If you are old enough to have been around in the usenet and later slashdot days most of us techies assumed then that anything technically possible with a giant budget and no oversight that could be done was been done.
Echelon was "known" to exist for example long before Snowden.
Snowden was essentially useful to confirm that suspicion, sadly it seems to have had little impact on how anything is done.
NSA capturing all data was conspiracy level. But even the problems with having too much data to sift through, also turned out to be correct.
And of course, even more ahead of its time, having AI solve the problem of sorting through the data, is coming true today.
