Skoda and Citroen are not 'full factory' efforts right now because the parent company's have different motorsport strategies within their various parent groups (SKoda still feeling the hangover of VW dieselgate, and Stellantis in electric) and therefore they can't get sign-off for a factory effort.

But, they have enough funding to be able to run customer-focused (but supported) operations. So they can afford to run the programmes and pay drivers and for cars etc, but can't politically say these are factory teams.

We all know Skoda is really factory, it's just presented differently for perception reasons....
