Power Designer surely is phoning home but this isn't nearly slow enough to matter here. AFAIK Visual Studio phones in during the operation, and not on startup. Libre Office almost certainly isn't phoning anywhere.
I didn't include the slowest starting software that I know, Oracle SQL Developer, because it's clear that all the slowness is caused by phoning home, several times for some reason. But that's not the case for all of them.
EDIT: Or, maybe it's useful to put it another way. The slowest region on the world for me to ping is around Eastern Asia and Australia. Some times, I get around 1.5s round trip time for there. A minute has around 40 of those.
