I don't buy that at all. That is an awesome program that I did not know about. However, they also support Gemini PDA, which is only one of Planet computers devices. And Pixels are well-known to be the among easiest to flash devices out there, and there is no shortage of third party ROMs available for them. From what I read on the SF forums, it's a sort of google boycott despite the fact that flashing a rom gets rid of the google in a pixel.
Right, but I offered you a counter-example in the Gemini PDA, and an indication that there was generally no effort - or positive resistance - to deal with anything google related at all.

Further, look at the list of devices they work on - not at all a list of phones easier to flash than a pixel.

There seems to be a lot of politics in their forums (and their past funding), something that does not interest me in an OS project.
