@nantes Well, there isn't much on Reddit to view at the moment since over 7000 subreddits (communities) have gone private in protest.
The TL;DR is:
The Reddit admins are imposing fees to use their API pricing out all 3rd Party Apps. Some estimations see the developer of a 3rd party app having to pay $20mill a year to keep the app working.
Meanwhile, the official 1st party app lacks fundemental moderation tools and has major a11y issues. Things that have been promised for years.
