Maybe spotify downloaded a data breach and ran it against their db to force better password practices?
My user/default password plaintext combo from when I was 15 was leaked in some EA hack a long time ago. That caused such a headache that I stopped using the same thing everywhere except free services. This initially included spotify. Then I upgraded to premium, and about a month later someone was trying to kick me out of my account (listening from their device) and kept playing weird music. Now everything has its own password. EVERYTHING.
Imagine if this trade war was a big ruse to force Americans onto iPhones and Chinese onto Huawei phones. It'd reduce the fear of other nations spying on your residents, as well as increasing the coverage of your own national spying capability. It's win-win as far as both presidents are concerned. Maybe they'll declare the trade war is finished once they are satisfied with the uptake of spy-enabled hardware in their countries.
