When someone says "we didn't have..." and clearly we did have, chances are pretty high that you simply weren't aware of it existing. It ain't because I'm older, I was just aware of it, maybe you weren't. That's what I put forth. There are older Millennials that would agree with me and those that would agree with you; it all depends on what their experience with the internet at that time looked like.
My little brother's (early Millennial) experience is gonna be different from my baby sister's (mid/late Millennial) experience, and the both of them will greatly differ from my oldest daughter's experience (very late Millennial). My brother might agree with me whereas my sister and daughter might agree with you.
Well I never said the access was never there or non existent. Just the ease to which it could be accessed. Yes it could be accessed through computers and later cell phones. But that all took time for people to have more personal home computers and cell phones that gave that kind of access.
