No harm in making one's thoughts known.
However, never forget the audience.
These are the same kind of people who vilified Ed Snowden for revealing their game to Americans.
And, before Ed Snowden was James Bamford whose book Shadow Factories 2008 explained how the No Such Agency basically monitored all electronic communications. His reports on how the government used an optical device to split the beam of fiber optic cables without loss or noticeable reduction of signal is chilling.
So, these people who claim to want to hear Americans on encryption have had tons and tons of chances to stop pulling their stunts before now. Their real intent is already manifest.
Even the latest revision to the law about collecting meta-data on phone calls is misleading. The government offers to stop collecting, but requires telecoms to retain the data for five years and requires the telecoms to turn it over without a warrant when requested. Total subversion of the warrant process. Not even a FISA court warrant. But, it sounds heartening on the surface because the government will (so it says) stop collecting. And, we know how fast the telecoms turned over subscriber data several years ago secretly. And, how, even though illegal at the time, Congress passed an unconstitutional ex post facto law making what the telecoms did retro-actively legal and thereby destroying the ability of anybody to sue.
These types of people have told us over and over again their real intentions. It takes no genius to estimate the sincerity of their request to involve Americans in a discussion on encryption. Oh, they may want to involve Americans in a discussion on encryption, but whatever their real motive, it ain't gonna be good for Americans.
