The subreddit has been set to private for the 12th-14th of this month in the protest against the API changes and how they were implemented.
These changes are going to make 3rd party apps unviable and will negatively impact the user experience of many users that use these apps to access the site. Of non desktop users (around 50%) over 70% of the users are accessing the sub through non 1st party apps. This means a large portion of the users of the KiA sub are going to be negatively affected.
While most people can understand the requirement to update API charges with the increased use of LLM's that scrape sites like reddit for data to build their models the way that these API changes have been implemented has been in a way that will negatively impact the users.
