I’d like it if it looked like a head-crab.

Does it block infrared sensors as well?

Don’t have a smart speaker - don’t want a smart speaker. But if I’m forced to buy products due to it being the only option in the future; I’m thinking that an ice pick would be cheaper than this.

Nifty fix for a problem in a product I do not need or want.

A friend did a network teardown of his google home and found that it wasn’t using the network at all until the command phrase was issued. I don’t pretend that it’s not a vulnerability, but that vulnerability doesn’t mean it’s transmitting everything you say to the mothership.

I see it as more of a prophylactic than parasite.

DMCA lawsuit in 3…2…

Seriously, if I’m stuck with one of these things in the near future, I’ll be looking in to it.

I doubt enough of these parasites will sell to matter to the larger companies.

I wonder if the speaker could sample the white noise and then invert it to cancel the white noise and get back to spying as usual.

Is it copyrighted white noise though?

DMCA? As far as I can tell, the device is completely external to the speaker. Why would DMCA come into play?

I’m pretty sure more tenuous “subversion of use” claims have been made. After all, they don’t have to be right, they just have financially defeat their target.

So you want a method to stop your smart speaker unintentionally activating until you actually want it to.

Switch it off?
