I think it's par for the course for user traffic to normalize since the platform gets visitors just by simply existing.
But if they actually matched that against old users of the site, then it actually means something. Most of the users that left are usually power users and have used Reddit long enough to use third-party apps and can't stand the bullshit changes.
Once upon a time, I used to care and disabled adblocking by default.
But then they tried adding malware and ridiculous amounts of requests to third-party sites I didn't consent to share, and is actually consuming metered data on mobile back then when unlimited data wasn't an option.
So yeah, I'm adblocking by default now that it's been abused and it's necessary for self-defense.
I eat my crusts but I have to admit, those who do not have a good point when some pizzas out there have especially terrible crusts.
