I mean, they accomplished the first part mostly because they are cheap connected speakers, but I have yet to meet anyone who doesn't absolutely loath their home assistants. Got rid of mine (Both Google and Amazon) not just because they are a privacy nightmare, but because they are completely fucking infuriating to work with.
The exact same phrase is never guaranteed to have the same results. The assistant hardly ever answers a question right. It routinely takes repeated attempts to get it to control any of my connected lights. It responds to people that weren't talking to it. I could keep going...
If they tried charging me for it before I rage quit them, I would have just rage quit sooner.
