This very much reminds me of the restaurant up-the-road from me that changed their entire menu and put it on Instagram only.
When my to-go order was grossly incorrect (website not updated), they told me "nobody uses websites anymore, we put our info on Instagram".
I assured them that lots of people don't have Instagram, and I haven't ordered from them since (because I don't know what they sell anymore).
I might be "out-of-touch", but I'm also not spending my money there anymore.
