This is mostly true. Verizon does have a say in what goes into the build (i.e. all of its bloatware). It is a Verizon branded phone and they own the network. However, I don't think Verizon would purposely prohibit double tap to wake. They have nothing to gain. I do think they would lock down the APN settings though. This discourages people from buying Verizon handsets and using them on competitors networks reliably. I'm not sure if they are locked down on Android and Apple devices.
I checked my wife's GS5 running Lollipop and couldn't find anything about setting up MMS, just APN settings. Even then I could not set up a manual APN. I can set up an APN on my Icon though. You have to turn it on in SIM+cellular, to set up an APN.
As far as double tap to wake, a little research showed me that there are stability issues with the 930 using double tap. So maybe Microsoft decided not to enable it on the Icon because of that.
