That's a good assessment. Essentially there was a period of 'The Internet' before the corporate websites took over where it felt both vast, and unknown. Nothing had a Facebook page/Twitter feed, or an app, so everything needed its own website, and within those websites were more pages, links, and locations.
I know there are small places like this one where people still communicate like real human beings (within reason), but so much of the The Internet is now presided over by advertising and media giants that it feels like a far less expansive, or uncharted territory. Facebook welcomes you with cutesy, emotionless phrases. Google can't load a page so it sends you a little emoji. Twitter offers "suggested" feeds. Everything is bought/sold and courier-delivered online, through phones, devices, earbuds etc. to the point that it doesn't feel like a place where people have freedom of expression any more. That's okay, I was always a take-it-or-leave-it person regards The Internet, but it's odd how relatively swift the corporate takeover has been, and as you said, there's now people in their twenties who grew up like that, and to whom it's completely normal.
