That's about all I need as well. Then they take those basic functions which they are very good at and started trying to push other usages. "By the way, did you know dogs are blah blah blah."
Fortunately, they seemed to have backed off on that a bit. It was a good reminder for me though - they control all the dials and can take something I bought and enjoyed using and enshittify it at the drop of a hat.
You can say "stop by the way" and it'll stop for some inderterminent amount of time then come back. I've heard that some people set up a Routine at 3am every day to turn the volume to zero, say "Alexa stop by the way", then turn the volume back up. I haven't tried it but I heard it works.
