Makes sense that users document what they do.

Makes sense that developers document what they do.

You really expect users to understand and document backdoors better than 
the developers implementing them?!?

Why on Earth would I suggest it otherwise?

Speaking for myself, I got discouraged when we met in Bavaria and it 
became clear to me that your avoiding OSHW certification was a 
deliberate business choice.

Don't get me wrong: I respect your choice, and I have not totally lost 
interest, but I prioritize OSHW devices higher - e.g. decided to devote 
time to get the Olimex Teres-I laptop in working shape instead of 
grabbing the already mostly working PineBook which is lesser free.

RPi isn't in a vicious circle, so no contradiction there.

Here's my recipe for Pi: Create a charitable foundation and partner with 
a) a university vouching for your noble cause and b) a chip maker 
needing brand value of a noble cause while keeping control (by offering 
large discounts only for charity).

Yes, just as Debian had waited for years for your collaboration (first 
release dates back to 1993) but you decided to compete with LetuxOS 
instead of joining and improving Debian :-)
