Let's keep some perspective here. By "eavesdropping", you mean a small handful (~4000 devices) of first gen devices that
were never sold to actual customers with defective touch sensors causing the recording to be activated.
The software fix pushed out simply disables the "push-to-talk" feature entirely.
Unless you think Google has some kind of motive to listen to completely randomly-triggered recording (and they don't; the data would be garbage from almost any standpoint I can imagine), your post is incredibly misleading at best and malicious fearmongering at worst.
