you can't stop ALL ppl from doing stupid shit.
I think, you can't stop them too. :-)
plus, federated servers don't change the source code and force all of us to scramble to adjust our strategies based on a disruption of the mining equilibrium as well as user disincentives to further utilize Bitcoin as Sound Money as it will have been broken by an SPVproof.
Bitcoin is not source code. Bitcoin is protocol and blockchain.
1. Source code of software (what works with bitcoin blockchain) is changing every day. (Bitcoin-core, Bitcoin-qt, Electum, MyCelium ... )
Bitcoin(in term of sotware) is open-source; its design is public, nobody owns or controls Bitcoin and everyone can take part.
2. Everybody can change and distribute "free software" to anyone and for any purpose.
@Adrian-x Yes it is ethical that for-profit company creates software. Look at Microsoft, Apple, Google, IBM, HP, Samsung ...
