3rd party reddit apps rival reddit's own app in terms of popularity, and will be significantly hamstrung by these changes if NSFW content can only be accessed in the official app. Lots of non-porn content is marked NSFW. It may end up having a much larger impact than reddit corporate anticipates.
I think that's intentional. They clearly want to kill those apps because they don't generate ad revenue. Those apps will now also have to move to a subscription-only model because the APIs will be paid, as the Apollo dev confirmed.
It wouldn't be so difficult to swallow if the official mobile app was high quality, but it isn't. There are major UX issues with the official app that haven't been fixed for years. The 3rd party app ecosystem is vibrant because of this. Instead of competing and being the best on merit, they have decided to play their platform-owner veto card which is very disappointing, compounded with their dishonesty about the true intent of these changes.
