What will be interesting here is how fast it falls off HN.
You assumed wrong. A moderator changed it because the submitted title ("Yuri Milner's money is from Putin (via Gazprom, oligarchs, et al)") was an obvious violation of the site guidelines: https://news.ycombinator.com/newsguidelines.html.
We often put individual names back in HN titles when the audience here can be expected to recognize the name. I've done so above. That's a rather specialized moderation practice, which not everyone who edits HN titles knows about. The basic edit was valid and routine.
Remember your priors.
