There's plenty good reasons to have microphones in products. The simple obvious one is voice control. Legality and illegality all depends how it's used and controlled. And the company is controlling this remotely.
And your rank and file engineer or software dev is going to have low/no understanding of the subterfuge and illegality that the Executive class puts together as a final product. The features are possible, but the labor only knows their pieces. Executives are the ones selling illegally gotten data to "their 500 sponsors".
