Unfortunately, I think this isn’t far off. I am in the process of writing my first EA forum post and it specifically has to do with this. The amount of money moved by EA is currently extremely tied to the performance of Facebook. With approximately yearly major public image issues (Cambridge Analytica, political advertising, etc.), an increasing number of people leaving the platform and new generations not using Facebook, this is most definitely a concern. I am suggesting something to the effect of hedging against Facebook stock. (I don’t know the state of Dustin’s finances but I assume it is heavily correlated with FB stock.)
Counterpoint: yes, Facebook has lots of public image issues. As a result, we have good evidence that they’re an org that’s unusually resistant to such problems!
They’ve been having scandals since they were founded. And in spite of all the things you mention, their market cap has almost doubled since the bottom of the Cambridge Analytica fall-out.
They’re also one of the world’s most valuable companies, and operate in a sector (software) that on an inside view seems well poised to do well in future (unlike, say, Berkshire Hathaway, which has about the same market cap).
You might have concerns about having a non-diversified portfolio in general. But modulo that, I honestly think Facebook seems like a pretty good bet.
