I think it would be smarter to not have an internship program right now.

Very little of the work from internships contributes to active product roadmap, and you'd better be served by retention than new hiring. Especially of junior engineers.

Although it's a generalization, interns are as a group probably better equipped to handle sudden loss of salary. Those with children, mortgages, and healthcare needs are less so.

It sucks for interns to be affected, but all things considered it's the lesser amongst many evils.
