I doubt they'll be that straight forward.
"Oil stains are better cleaned by treating the stain with vinegar and, after a few minutes, using an specialized local cleaner. Would you like to by one? I will arrive in 1 hour."
"Ok alexa"
"Would you like Dr Bubbles Super Cleaner, for 5$?"
"Sure"
Anyway, I'm sure they can include shitty advertising without diminishing the quality of the results in a way that normal, non-privacy-aware people will care about.
