It doesn't seem like that to me. I believe the decision lies elsewhere, maybe on the cost of licensing USB-C everywhere or even an overstock of Micro-USB connectors they have to use.
I do believe the transition should be faster. As I said, I'm a great supporter of the "pull off the Band-Aid" method. That said, I don't buy tech all the time, and the only device I have with an USB-C connection is a GoPro Hero5 Session - and I bought an Anker USB-C cable for it.
Do I believe USB-C should be mandatory in new products? Yes, absolutely. Do I believe it's a dealbreaker if it doesn't? It depends. It's not like we are transmitting large amounts of data and energy to our speakers, for instance. But a new projector? That one should have USB-C from the start.
