The RedReader app has been given accessibility status by the graciousness of reddit and will not have to shut down. The dev is not particularly happy about how fellow devs were treated though and still plans on adding lemmy in future. Read the announcement here
I suspect support will be axed eventually - chances are many people will flock to these exempt apps to still get their 3rd party client fix, and that will put them on the radar for Reddit to find a way to justify pulling the rug out under them too (e.g. “Our app is now accessible!”).
It’s a shame that Reddit went like this.
