I wish that your project would support more devices. The fact that you only support Google devices makes me more than suspicious.

You want me to use devices from the world's most devious manufacturer that does evil. To have the most secure and privacy focused android ROM experience on. 

Sure you are trustworthy, so far at the software level at least. However you run on proprietary  hardware that I could never trust in a million years trust. 

Why? 

 Their website spells out in every conceivable detail why they currently support Pixels only. Also, name one smartphone with fully open source hardware - you cannot because there simply isn't one. Seems your suspicion is unfounded.
