>Unlike bitcoin, it is able to do large changes, since there is a completely different development culture

Can be read as: a 'relatively' small group of people control the protocol to such a level that arbitrary changes can be enacted with relative ease.

An example that comes to mind is Ethereum, which is essentially controlled by a single developer aided by a few others. When a bug in a contract would have cost many people a significant amount, the lead developer lead the charge (to the applause of almost all) in forking the chain.

I haven't looked at Monero in enough detail to confirm this, but your statement is not exactly a selling point. Having decentralization to the point that it becomes hard for developers to force through changes, should be a feature... not a bug.
