I have the impression that despite the knowledge that his leak brought us, many have gone back to 'business as usual'. But if I take it seriously, I would have to assume that all the traffic I am generating is being logged and stored for an indefinite time, and that various international intelligence agencies have direct access to the data stored on servers of all major cloud providers, negating the usefulness of 'https everywhere' and similar approaches to encrypted transmissions.
So I'm curious how you changed your online behavior in the past six years. Do you store all private data on your own servers? Do you take additional measures with regards to encryption, in storage or in transmission?

For me he made the Great Game of Privacy a lot fairer. You should read the excellent entry on Wikipedia about the aftermath of the leaks[0]. If the leaks meant that privacy-loving folk went 'dark' in light of the leaks, then this is a net plus. Snowden's actions possibly hindered NSA in catching undesirables, but it's a small price to pay for a bolstered Internet and privacy-respecting comms. And who's to say that the apparatus even worked that well in foiling the efforts of plotters? Bill Binney[1] consistently drives his message home that the NSA's surveillance apparatus is very inefficient at foiling plots, and I agree with him.
Even if it stopped one plot in all the time of its existence, it's still an enormous effort and an enormous amount of money spent just to foil one plot. Old fashioned police work is better at foiling plots because it doesn't have to rely on big data algorithms sifting through the noise of Internet traffic (most of which is innocuous). Old fashioned methods work because they employ simple detective work - it doesn't need the NSA at every choke point and decrypting countless crypto.

Perhaps these assist your question more than this harangue.

I was disappointed in the NSA's security though.
