The main thesis of the article is outdated and now wrong - as someone pointed in its comments: https://github.com/btc1/bitcoin/commit/a3c41256984bf11d95a560ae89c0fcbadfbe73dc https://github.com/btc1/bitcoin/commit/a3c41256984bf11d95a56... All the rest might be interesting to someone completely new to the subject - but it also contains many mistakes. One is confusing git forks of the source code with the blockchain forks. Another is his claim that "everyone agrees that the capacity of the Blockchain needs to be increased" - bitcoin needs capacity increases - but it does not need to be on-chain - there are proposals like Lightning Network that would do that off-chain.
