> Like, 90% of sites are encrypted now How much does that have to do with Snowden vs. Let's Encrypt.
It's not just the Internet traffic being encrypted, it's the proliferation of alternative services that have popped up because of the leaks (Protonmail, Tutanota etc). Many services exist now that are because of the revelations, and it's not just about HTTPS. You can very readily install many tools & utilities that thwart the NSA dragnet. Think Signal, Matrix, Cryptomator, self-hosted Nextcloud, AD-blockers like uBlo…
That's the narrative but doesn't really hold up to scrutiny.
> Signal
Moxie's original encrypted messaging apps date back to 2010 and Open Whisper was officially started in Jan 2013.
> Matrix
Came out of an effort to build a unified communications suite for corporations.
> Cryptomator
Never heard of it. More widely used solutions like Attic/Borg have been around since 2010.
> self-hosted Nextcloud
Nextcloud was forked from OwnCloud which was started in 2010.
> AD-blockers like uBlock Origin
Ad Block Plus has been around since 2005. uBlock Origin solves the same problem but does it better. Claiming this had anything to do with Snowden is a very tenuous argument.
