And they're welcome to read those at the library or other sources - eBay, as a company, is under no obligation to facilitate dissemination of historical documents.
I thought that ebay was just a website where people could sell their historical documents to each other. Ebay does not "disseminate" the things that people send to each other. Heck, it doesn't even deal with the delivery! It just processes the payments. Why are they willing to engage in editorializing stuff that they don't even see? It makes no sense.
Ebay is a company, not a website, and company policies specify which products can be listed by their users. It's not neutral, you're being deliberately obtuse here.
