I really wanted window 10 phones to take off. Their development into their now defunct projects such as Continuum and Munchkin in my opinion could have jump started and sustained smartphones as a legitimate productivity PC. Imagine having a cellphone you can dock anywhere and have a full blown windows OS to do things on…. That’s where they were heading.
Alas, the best we got is Dex and stage manager both being cellphone OS solutions for work PC tasks.
Knowing someone working for one of the three services you named…. They don’t really care. The people at the counter can’t accuse you of anything unless you are dumb enough to say you are shipping weed. After that, I would assume shipping is laxed due to your mentioned reasons.
