I have a large ice chest and a heavily restricted diet due to medical issues and my food banks won’t give me fresh produce unless I show proof of residency (they want you to have a refrigerator). The little daily snack pack with oreos and soda they give you otherwise isn’t worth the trip.

I’m sure a lot of military software, in contrast, is acquired from private companies that retain IP rights. Likely legal exceptions aside.

There’s an option to donate on their website here: https://donate.wikipedia.org/ I’m starting monthly at $5 and possibly bumping up to $10 later on.
