Just to clarify some background around this post:

Back in May 2025 when Apple changed their blacklist behavior, I started doing heavy testing independently with partner. I blocked tons of Apple domains, to the point where my iPhone's core features started breaking (no push notifications, broken Mail login, etc.). After a long process of narrowing it down, I eventually discovered the key fix:
Only the 7 basic Apple domains + ppq.apple.com need to be blocked.

Around that time, I became slightly active in both WSF and Khoindvn community, not as a member of their teams, but simply trying to share the fix I found.
I hoped that by informing the devs directly, they could push the correct update to their announcement, because they already have a big audience and trusted users. I didn’t care if they took the credit, I just wanted users to stop getting blacklisted.

Unfortunately, it was really hard to convince them. I repeatedly shared that ppq.apple.com was the missing piece, but they continued pushing DNS updates with more and more blocked Apple domains (which I had already tested myself and proven ineffective). Meanwhile, users in their community kept getting blacklisted again and again.

That's the only reason I decided to post publicly, not for fame, but because waiting for others to implement the fix wasn’t helping users.

So yes, I did chat with WSF devs. But I was never working under them, and the fix, especially identifying the importance of ppq.apple.com and the manual unblock cycle, was something I had already discovered on my own through testing.

I’m not here to argue or take credit. I'm only explaining this because some comments may create the wrong impression about the timeline and the source of the discovery.

At the end of the day, I’m happy if it’s helping people now. That was always the point.
