Recalibrate your weights toward more recent developments (post '21) and you will see a clearer picture, I think. M7 is quite popular now for TinyML applications (600MHz for an MCU!!). It's somewhere between RPi 2 and 3 based on Core Mark score and what I've seen in terms of CV capabilities. Things are moving very fast imo. MCUs can do 1080p at 30fps now and not just from faster hardware but with some impressive additions to instruction sets! Edit: After re-reading I see that you're talking about adoption rates, in which case, fair points.
