I looked at the Reuters story again, carefully, and

I couldn't discern any indication in the cited story via Reuters that it was 'initial in respect to Harvard University contributing more' -- except that the 100,000,000 was drawn from current endowment to establish the fund. Salting the fund with resources from the current endowment is a little bit unusual I believe because endowed funds are more often initiated by external donors. My hardly deep understanding of university endowment is that they are opened so that other people and institutions may donate to them. I may be splitting hairs here and I am totally relying on the cited story.

"HMC, which invests the University's endowment and other financial assets, revealed that during fiscal 2021, the endowment's value increased 27 percent, to $53.2 billion; during fiscal 2020, when the pandemic began and the economic outlook remained uncertain, its value had appreciated 2.4 percent, to $41.9 billion."

"Harvard Management Company returned 33.6 percent on its investments for the fiscal year ending in June 2021, skyrocketing the value of the University's endowment to $53.2 billion, the largest sum in its history and an increase of $11.3 billion from the previous fiscal year."

Again, the .1 billion allocated to initiate the fund is barely a pittance in my opinion, especially in light of the outsized pandemic windfall. I find the argument above reflecting the presence of many restricted funds to be rather unconvincing inlight of the huge return on endowment of 11.3 billion.
