I guess what I meant by "hard to know" is less confusing. All the names in your example cannot be easily confused with other product or brand. But "Google One" is the other way around.
If this is really the case, then I would say the name sucks. It's hard to know what 'Google One' means from just the name. And there is 'Android One', which is designed for low-end devices, it would really confuse people when they talk about android one, google one. I can see more people will refer it as "google one drive", and microsoft also has its "One Drive", that's even more confusing to all the average users.
