It's more that the weaknesses in iPadOS have received unanimous disdain by influencers who help sell the hardware, which is one of the factors that Apple does listen to (e.g. resulting in the iMac Pro and Mac Pro), and the pandemic/WFH likely affected the dev cycle a bit as it has with almost every other tech company.
