There's a (claimed?) stereotype that Millennials don't buy things on their phones, even if they are already browsed to the "buy now" page they'll conduct the actual transaction (and perhaps comparison-shop) on a laptop or desktop.
It makes sense to me, so I'm not sure if it's actually a reverse-dig accusing younger generations of doing the opposite and being unthinking consumers.
Either way, it's interesting when you consider how some "social media" (i.e. Tiktok) may partly be about changing how people shop, rather than (just) profit from ads.
