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.

I don't consider e.g. Android phones to be embedded. A smartphone is much more like a small laptop. That being said, there is a sliding scale; e.g. car infotainment systems have properties of both embedded and non-embedded software.

The grass isn't greener on the other side of the fence.
