Not exactly a shortage, no. But giving away an entire range without giving ample time (think months/years) for network operators to comply is a bit harsh.
Thanks for the link to their grants. It's good to see they're doing something useful with the money and it's not a case of outright corruption. Although one could argue a club from one of the biggest colleges in the global north may have more suited avenues for funding, i'm glad to see smaller projects in there as well.
To be fair, if the goal was to raise money for the community, would it not have been wiser to rent the IP space, or to setup a proper charitable auction? The IPv4 addresses are bound to go up in value in the coming years, now that major RIRs have given away all the remaining blocks, so that might have brought more revenue.
Also, they are giving back to the community. The largest grant so far was $1,620,000 to save a radio telescope for the MIT Amateur Radio club.
