I wonder what stopping three letter agencies to secretly push for keyboard manufacturers in such way that each keystroke has unique sound and it becomes easier

I wonder what stopping three letter agencies to secretly push for keyboard manufacturers in such way that each keystroke has unique sound and it becomes easier to detect keystrokes.

no need, keystrokes are sufficiently unique. even if its not, enough decent fidelity data with letter/word frequency analysis paired with small Neural net will quickly disambiguate keystrokes after the first paragraph.

If you are such a person of interest that the government is observing your computer usage, the game is already lost.

  The problem is, as stuff becomes easier and cheaper, usage becomes more widespread. DNA tests used to be in the many thousands of $ range, so they were used for heavy crimes like murders and rape only. Nowadays, it's routine for police to use them for petty crimes like graffiti [1]. It's just the same for camera surveillance, mass exfiltration and analysis of just about the whole Internet's worth of traffic... even searching phones and datamining them is cheap enough these days that US CBP does it for travellers, and German authorities for refugees (until a court order stopped that crap [2]).

Because they already backdoored the CPU using the Intel "management" engine.

This kind of conspiracy theory mindset really just doesn’t stand up to any scrutiny. Every keyboard manufacturer is going to build this in without anyone ever giving away the secret? How many people have to be in on the secret for this to work?

  the problem with these rebuttals is that these types of exploits are regularly leaked (well on average: rather occasionally but in large batches, like Snowden leaks). its like saying, humans haven't reached the moon, even though humanity witnessed it in the sixties. sometimes peoples memories are short.
