That's not the same at all.

It is (was?) easy to control your browser's history. It is impossible to control what these devices send to google/amazon.

Your browser's search history only gets populated when you, well, search. These devices are collecting information 24/7, regardless if you are actively engaged with them.

I don't think your last statement is accurate. While the device is "listening" for the trigger words, it's not storing information. It only collects information you call upon it for. You do need to actively engage. I have not seen evidence of otherwise.
