Vans have put a lot money into skateboarding from paying for the Dogtown and the Z-boys documentary, building skateparks, holding contests in said skateparks, and the Austalian bowl-a-rama, running a Youtube channel and giving a voice to Jeff Grosso, paying in skateboarders to wear their shoes (including women before it became the done thing, and old guys like Alva, Grosso, Hosoi), etc.
Whether that is worth you deciding to buy their shoes is up to you. And whether it's worth them continuing to do that in the future is up to them.
