That would be a trap. It's healthier for a non-profit to have many small funders than a few large ones.

Part of the promise of open access and open science is that the information is free and open to all. Including robots.

I submit to open things because I want my material to be openly available. If I wanted restrictions, I would submit to gated journals.

Papers submitted to arXiv under its most permissive license should always be free, as in beer, speech, freedom. For researchers that contribute to it, that is the intention for a reason. It is to serve public and corporate good without restriction.

This isn't me siding with AI companies by the way; it's a slippery slope argument.

as if they would pay.... they would pirate the contents as they already did
