This has nothing to do with transparency.
For some reason Elon has chosen to do some Twitter code debug in public at the behest of some of his followers.
Rather than just a cursory “we’ll look into this” he seems to be trying to verify the claim.
I guess he thinks his engineers won’t believe him unless he can show them what happened to engagement on a Tweet when an account is made private?
It’s all very odd.
There seems to be continuous mystery and intrigue around shadow banning. It’s very odd! Who wants their Tweets seen, anyway??? Seems highly undesirable. This isn’t high school! I don’t know why anyone cares.
