Sameer Samat, president of Android ecosystem at Google, asked a TechRadar journalist why they were using an Apple Watch, iPhone, and MacBook:
I asked because we’re going to be combining Chrome OS and Android into a single platform, and I am very interested in how people are using their laptops these days and what they’re getting done.
Also, it will be a license nightmare. As far as I know, Chrome OS is proprietary and actual Android has proper open source license.
It’s only proprietary in much the same way as Android. That’s why there are forks like FydeOS.
Parts of Chrome OS are available, parts aren’t. Parts of Android are available, parts aren’t. Neither are really Open Source, but both have Open Source parts.
Same with MacOS and iOS. They’re doing the same shift Apple has done over the last 25 years. Build on open-source, and slowly pivot to closed-source binaries. The perception of openness lags for a very long time until people finally realize it has just become more proprietary limited crap.
