I deeply resent it when Alexa tries to upsell me something and I certainly would if it fed me an ad every time I asked it to do something.

And what's the alternative? A subscription?

Alexa certainly isn't useful enough to me to pay anything meaningful.

Make good speakers, improve language detection, improve music playback, simplify that stupid-complicated-always-rearranging Alexa app, decrease my curse-at-Alexa rate, make Alexa part of Amazon Prime or charge me an additional $20-30/year for simple audio processing services.
