Yeh, I put tape over any cameras, even on my phone, front and back. I do have an Echo but just for development/testing so it's off the rest of the time. In the longer run, it's not difficult to imagine the internet become essentially unusable for anyone with anything to lose. It cannot be protected. No technical means can work, because there are hundreds of millions of naive users on it who are wide open for social engineering style attacks and who don't know enough to take even basic precautions. And those folks can then be used to go after less naive users (the Web of Misplaced Trust.) And, where there are technical means of attack (and there will always be), finding victims can be easily automated, so being a nobody buys you nothing.
