Should we start a public petition?

EDIT: This is an idea that I’ve recently been advocating for; I just don’t know where to start. We have public parks, why can’t we have public spaces? Offer a contract every few years to be bid by large corporations such as AWS, or Microsoft. Administration by semi-public entities such as universities or NPR. Make it join the Fediverse to enable sharing of content.

What am I missing?
