Correction. Making equipment does not exactly tell the leadership. Patents ownership does. Any equipment makers pay high royalties to Patent owners. Royalties is the cash cow, without it makers are only earning the "blood and sweat" money, cheap labours. Chinese companies Huawei included were that cheap labours back in the 3G and partially 4G times. 5G has changed the landscape, but Qualcomm was (is?) still the leader in terms of patents as of early 2017 with 15%, followed by Nokia at 11%, Chinese companies at 10%, Ericsson by 8%. The figures may have changed today, but you get the picture.
Yes, royalties are a cash cow for the holders of the intellectual property.
But I'm looking at the bigger picture, which are the downstream companies producing building businesses around 5G products/connectivity, which will exist at scale in China first.
The profits from those businesses globally will amount to a lot more than the 5G royalties incurred, or the cost of rolling out a 5G network.
