Now that they have commercialized the project, I suspect a rebranding away from "Meet" is probably coming next. It is obviously confusingly similar to Google Meet.
On a more serious note, it was never confusing to me - I didn't even notice they share the same word until now tbh. And quick search for "meet videoconferencing" shows quite a few of the products named similarly. To me it is almost as generic as "chat".
