On the other hand...If you asked, 5-6-7 years ago, 100 people which of the following they used:
Slack? Zoom? Teams?
I'm sure you'd get a somewhat uniform distribution.
Ask the same today, and I'd bet most will say Teams. Why Teams? Because it comes with office / windows, so that's what most people will use.
Same logic goes for the AI / language models...which one are people going to use? The ones that are provided as "batteries included" in whatever software or platform they use the most. And for the vast majority of regular people / workers, it is going to be something by microsoft / google / whatever.
