I mean... it could be juicing metrics as you say. I certainly have no love for these companies. But more likely its to minimize support, confusion, and a feeling of brokenness.

Alice, Bob, and Charlie are in a group. Alice blocks Bob. Bob sends a message. Charlie responds to it. Alice says “what are you on about Charlie?” Because she didn’t see bobs message because she has him blocked.

Alice and Charlie work out via messaging back and forth in the group that bob sent a message and that Alice has him blocked. That’s awkward for everyone. And happens every time bob sends a message in the group.

How would you deal with that?
