They can copy and paste the code. However, there still needs to be changes to it to adapt to what Steem has. Plus a lot of it was coding tied to the infrastructure that is being used.
So there are a lot of moving parts to these blockchains and simply copying code is not guarantee that it will all work with what is already there.
Plus the applications are separate. They are layer 2.

Thank you for your reply Task! The diversity and differentiation of Layer 2 may be the Assets that count in the Future. Once the underlying Blockchain is not noticed by the user and interchangeability of tokens across chains is normal, the worth of the chain may mostly depend on the ecosystem build on it. Interesting times ahead.
I think that is a good summary of how it will work.
Look at Ethereum. The token is flying because there is a ton of stuff on there.
However, the DeFi is developing its own value.
