The entire time since that announcement last year dropped I have been using the modified Infinity for Reddit client that has my own API code in it.
I told myself if that stops working, whatever, I will not try to keep the app up to date and I will not switch apps. Lemmy works well enough for me now.
Up to this day the few times I have been accessing reddit through it I have no issues whatsoever. Amazing. Then again I never tried while they had issues with their official app, I suppose. Unless that is right now as I type this, because right now my app is still working fine.
