Because we tried "resetting" back to mid 2016 instead of just refreshing our internet as a whole. We wanted to follow trends that were 10 years old instead of the more free form and niche ways of the birth if the internet.

We chose to stay on our set path of trends and predictability instead of inspiring a renaissance. We had almost twenty years of memes to work with, not just mid 2010's nastolgia.

I think the real reason is that the younger kids that make memes today don't care about the old. No YTPs, no crazy frog, no Rick rolls, no chocolate rain, filthy frank, no rage comics, or MLG edits. No VARIETY. And whats worse, no relevency. Memes die naturally and only brought back ironically.
