Maybe. As a new manufacturer, Bollinger has its work cut out, but GM hasn't exactly been a mover or shaker when it comes to EVs. The first attempt to slow adoption was their hybrid (Volt), and the EV (Bolt) isn't exactly inspiring. Nissan (for all the faults of the Leaf) takes it seriously, GM just wants EVs to go away.
edit to add:
I get it, its a puff piece. But the target market for Hummers doesn't give a hoot about environmentally friendly, no icing on that cake. Brand name could help sales, sure, but they are exaggerating the synergy.
