Can Someone Explain Bambus Life Cycle Guarantee Policy For The Current Generation Of Printers?

I had someone in another post I made mention this. He said there are close arriving deadlines to the guarantees on updates and spare parts for current gen printers like the X1, P1, and A1 series. Can someone explain this, and the impact it may have on new and long term users? I don’t want to buy if I can’t be guaranteed a proper functionality timeline for my purchase, or no way of getting replacement parts as their ecosystem seems to be very closed off. Thank you.
