Tampering? That's harder. But to protect against corruption, since the hashes are shorter, you would be able to chisel them in different types of stone and glass and make 3+ copies of them. I suppose if you really want to protect against tampering, you could distribute so many copies that the ability to tamper with a majority of them would be very unlikely. But I think what was meant by "publishing" was that the hashes would be available to parties who would be willing and able to preserve them indefinitely.
