But McDonalds does use other meats than beef in its burgers. It utilizes the meat that is localized to the region. As of ~ 10 years ago when my wife worked on a McDonalds account they used Zebra meat in regions of Africa. In the US that would be considered unacceptable, but then the cow is considered unacceptable in other areas (e.g., India). Not saying worms is in their meat (intentionally), but if it makes financial sense, I guarantee they will have looked at it.
Similarly, Amazon and all others aren't giving you a smart speaker for nothing because they are generous or want to make sure you have the best home AI you can. They are doing it because it makes their sales of other products increase AND because they are using your data (voice commands etc) for their benefit. If you are ok with that, then cool. I don't know that anyone here has said Amazon is listening to everything you say and using it against us (spying). It is clear though that if you have an internet connected speaker, it is possible with the right techniques to exploit it. That's not to say Amazon is doing it though. And yes, there wouldn't be much interesting going on for most speakers, but that doesn't mean it isn't possible which is what the general discussion here has always been. No tin foil required to comprehend that.
