I still have my Mk3s too. But, there was a a harder learning curve to getting a quality print from that Mk3s than there is to the Mini/AMS combo I have next to it. And casuals want that ease of use. Just unbox, plug it in hang a spool of Bambu branded filament with RFID then slice and print.

Like it or not, few people want to spent time running calibration models and temp towers. Raging against the sea is a losing battle.
