“Hard fork” is a term that often incited heated debates. Some communities explicitly embrace on-chain governance, such as freezing accounts and changing smart contract code on-the-fly, while others are known to be firecly rooted in the “you don’t hard fork, ever” fork camp.
The Bitcoin community has a reputation of strict hard-fork-averseness: Major changes on the protocol level usually don’t make it into the mainline Bitcoin Core client (i.e. hard forks are always contentious and lead to splits from the main BTC chain). While this makes it hard to implement meaningful protocol updates, it also creates confidence into Bitcoins’s reliability and the finality of Bitcoin transactions.
