Kbin.social need not be anti-corporation, but setting standards that fellow federated instances must abide by / putting into place a "collective treaty of federation" or some such that sets the terms of federating with kbin.social (and other signatory instances) would be exceedingly wise. In theory, I have no problem seeing commercial entities as part of the fediverse. In practice, though, I'd want to see strong protections in place to prevent them from turning the fediverse into "Social Network Inc, but hosted on everyone else's dime.
