I understand what you are saying, but it is standard blockchain terminology for all blockchains, not just the Steem BC. It is meant to sound aggressive as it is a radical, a very big change that makes the old versions of the blockchain [partially] incompatible with the newer ones. And it is a fork, as the chain [temporarily] splits in 2.

There is a soft fork, that is mainly used for bugfixes etc (for example, when the Steem BC went from 0.19 to 0.19.1)
