Without the fuzz over enough time passed we, even NSA experts, seem to forget about those traps.
The moral of the story for us techies: Don't wane people in anonimity if they use X or do Y. There will be a percentage of people who do things, they wouldn't have done without that info, and some of said percentage will be blackmailable (think miners having "inciminating pictures" on their machines because they were stored on the blockchain once).
Worse than a privacy infringing government are blackmailable citizens (One could argue the former causes the latter, I argue the latter steers the former into worse).
