Earn It act is adorable little attempt at institutional police state policy.
One would argue that terrorists will simply use other inventive ways to get around lack of main stream encrypted tech (and they will). Or that a back door for the govt is a back door for anyone (which is true). Both are logical points.
I posit that this is known among backers of Earn It - they're not that dumb. Therefore, this isn't about child porn or terrorists, its about dissenters of established institutions (government, corporations, media, etc). That's the move - the "party of Davos" sees the populist wave from both left and right (AOC, Bernie, BLM, Trump, Bannon, etc) and this how they think they will stop it.
The next AOC, BLM, or any populist movement will be labeled as threats to the established order, maybe as domestic terrorists. With Earn It, you can see who they organize with, when they meet, how they strategize, etc. This is COINTELPRO with smart phones [1]. Very slick, very effective. It's what I would do in their shoes.
The only flaw is that it is poorly marketed. It's so transparent, it's cute.
J Edgar Hoover is smiling somewhere in the after life.
Do yourself a favor, treat your phone and email like CIA recording device. We'll be fine.
