As someone who went through similar challenges with Google making it impossibly hard for BlackBerry to provide an Android runtime on BBOS10, and now running GrapheneOS, I trust Google exactly zero to do the right thing by any open source project it stewards. Combined with their other practices, and lack of ongoing support for their commercial offerings, means that my perception of them is irreparably damaged and I minimise my usage of their products as much as practicably possible.
Did you work on BB10?
No, I was a lowly consumer who still laments the demise of BB10. It was one of the best mobile operating systems I have ever used. Fast, stable, with a refined UI that prioritised efficiency.
