Did you actually work in the embedded industry, or are you just venting on some bad experiences you had with some boards/phones?
You know, embedded is more than r-pi clones and android devices, right? It's auomotive, aerospace, industrial automation, healthcare, etc.
I cannot overestimate how mistaken you are but you seem to be already set in your ways, and have a bone to pick so I'll leave the conversation here to save my sanity as you can't be reasoned with nor is anyone's time worth it to convince you otherwise.
