Facebook does own them all, so this is just them disclosing that fact.

If people were using Instagram or WhatsApp over Facebook branded alternatives because they didn't want Facebook to have their information, then all this does is demonstrate that that ship has sailed.

Yeah but public sentiment is one of the things driving policy maker to consider breaking up big tech. If Facebook make sits branding even more ubiquitous than it already is that's not going to work in their favor on this issue.

Public perception maybe, but regulator perception may be different - "You are misleading the public, and building a monopoly in an underhand and obfuscated manner. This is a misuse of your position."

Now that they are already looking at it, I suspect public sentiment may matter less.
