For example, I would ask Alexa "can my dog eat <X>". In the beginning it was not clear to me this was a third party skill. Then one day Alexa would respond with something like "nay, Dr. Wolf says ..." (I don't quite remember). I was surprised because who speaks like that? I then realized it was an Alexa Skill made by a third party developer. The developer later attempted to monetized this skill so you could only ask the question 3 times and after that it would bill you.
Alexa has a lot of other issues. Every room in the house has an Alexa Echo Show. But the screen real estate is entirely wasted with useless stuff. Very limited customization.
I'm in process of replacing my home automation with Lutron products. And the Alexa will soon be gone from my home. It seems like everything Amazon does is half-baked, but enough to get out the door. There is no polish at that company.
