Right, that's why they are called PHEVs (Plugin Hybrid Electric Vehicles).
What matters is how they are used. If PHEVs are used in their plugin-electric mode most of the time (why would someone pay a premium for one if that weren't the case?), then they are operating essentially as electric vehicles.

Unless one takes an oath not to ever be ferried in an ICE powered vehicle, I don't know how you can avoid indirectly financing the development of ICEs. Also, it's not like ICE technology itself is 'bad' anyways, just that its time powering mass market vehicles is coming to an end with the rise of battery electric propulsion.
ICEs aren't going to disappear as a technology, but will likely be focused on specific niches where they have utility, rather than in mass market vehicles.
