The "only 5%" is what distinguishes it from Chromium, so it very much matters. And, that blog post is what I meant when I said they are actively hostile to the FS movement. Basically, they say users do not deserve the freedom to fork because competitors and Bad Guys can use it - very ironic for a product that is itself supposedly "95% based" on a competitor!

The argument that users should not have the freedom to fork because bad guys can use it is very similar to the idea that users should not have privacy or anonymity on the internet because it will be abused by bad guys (the so-called four horsemen of the infopocalypse).
