Because the chip shortage in the automotive industry is well documented? Nobody is saying "Well I wouldnt expect to get a car I paid for right now either!" they're saying "News reports from multiple companies, sometimes in different industries, confirm what Square are saying about it being difficult to get new servers."
By all means be angry at Square if you want, but if you want to deny the existence of a well documented semiconductor shortage then you're doing yourself a massive disservice by denying reality.
