I think there's a deeper issue around paying customers being assumed to be businesses. I have a paid Google account for just one reason - using a custom domain with Gmail. This lets me have a wildcard email address, but more importantly, it gives me the ability to move my email address to a different provider if my Google account got caught in an automated system and blocked, so I wouldn't lose access to all the services I've used that email address to sign up with.
If there was a way I could continue to just have a regular personal Google account, but pay an extra fee to use a custom domain with it, I'd much prefer to do that than maintain an enterprise Google Workspace setup with only a single user in it, just for this one feature.
I think the lack of activity since the conspiracy theory started could be easily explained by the user being creeped out by the witch hunt and abandoning their account. I know if I was accused of secretly being a hated figure like Maxwell on an account that wasn't connected my real identity, I wouldn't come out and deny it, I'd just ditch my account and make a new one.
It also seems unlikely to me that someone like Ghislaine Maxwell would have the time to be such a prolific Reddit user, and that she would write like a Redditor - for example calling someone "butt-hurt" in one comment.
