Sure, but vans have been part of skateboarding since pretty much there inception.
Have a lot stronger roots than Nike and Adidas.
So I would say they are closer to a skate shoe company than Nike or Adidas.
That's a logic I commonly hear from people who are into (or work for) Vans, but reality, past all marketing ploys, is anchored in the present first and foremost especially in an industry as quick to update itself (sometimes) as the one of skateboarding. And in the present, besides the 'since 1966' act/hashtag, they are comparable to Nike/Adidas. I commonly hear people argue that Nike and Adidas have also supported skate events and skateboarders from early on and so on. I respect your consideration of their legacy, but from my perspective I think the lines currently may be blurrier than you think. Which I couldn't blame you for because Vans' strongest marketing argument since the Janoski has been how they're more 'core' but especially nowadays, that's essentially a fabrication.
That's coming from someone who would feel just as 'gross' skating in Vans as in Adidas and Nikes, so feel free to take this with a grain of salt. Plus if you're satisfied with what Vans currently does (and they occasionally do cool local shit), then more power to you.
