I think you’re right, but it’s hard to get large scale support for a new coin. Bitcoin cash had support, and they did ok with the fork, but it’s not worth anything close to Bitcoins value. They were even mining at a loss to keep it afloat. You really need people willing to mine at a lose if you expect to have a successful hard fork.
