They created a new business model for a new type of open source software. It doesn't do anything for all the existing types of open source software. Nobody is going to turn glibc into a blockchain.
That's just a sign of glibc being stuck in the wrong millennium more than anything else. Add a couple functions to create ERC20 tokens and add the EVM as a supported architecture and I'm sure that can change. It's high time to remove those unsafe APIs like strcpy and printf that cause CVEs all the time and refocus effort on things that actually matter.
Yeah like add features nobody uses for real and remove functions that will break thousands of programs used by millions of people
