Why does this whole article feel like an advertisement?

The biggest issue would be data retention. Reddit serves as a real world database that stores all the historical content and search engines like google make it searchable.

We’re talking about petabytes, and lemmy hardly has a few gigabytes.

Who is going to store all this data, even in a distributed environment, the bigger instances would have to store a few hundred terrabytes (per year).

This means they realize that whole search is so useless that people have to rely on reddit for actually finding something useful.
