My guess is that Harvard's philosophy about publicity has changed. I think initially there was a push under Amaker to be very public about who Harvard was pursuing, in an effort to get their name out there associated with higher level recruits.

Now that Harvard is landing those recruits, I think they are more reticent about making it abundantly obvious who they are involved with.

That's just a guess as to why Verbal Commits used to have everyone under the sun for Harvard in past years, and nobody this year (while it has reversed for Yale).
