Yeah it seems to be a totally clickbait claim, not even a single link to a single piece of hard evidence.

Also this "WarOnPrivacy" account is highly suspicious, most of the past 100 submissions are all clickbait-y titled and a lot are culture war focused.

While the article has an obvious point of view, it cites other people defending their view , with plenty of links, and even the response from Harvard ('we don't comment individual investments'). The person that Harvard hired to be their ethics monitor resigned over this. It's not some invention from the head of someone.
