Their expenses are still absurd given that, from my perspective they've literally done no improvement to the product in the last 5 years or more. Just maintain the API, have some staff to run the servers, pay a few admins to support the mods and feature freeze Reddit the site as much as possible.
It's way crazier that Reddit has 2k employees than that Twitter had 4k or whatever.
Edited from $2/month/user to $2/year/user.
