I agree with your observations, and that they both could and should do better. However, they have the privilege of being the AI company, the most hyped-up brand in the most hyped-up segment of economy - at this point, the impact of their naming strategy is approximately nil. Sure, they're confusing their users a bit, but their users are very highly motivated.

It's like with videogames - most of them commit all kinds of UI/UX sins, and I often wish they didn't, but excepting extreme cases, the players are too motivated to care or notice.
