No, you missed the point. They don't want Chrome, and if their aversion could be solved with small tweaks to the branding they'd have probably just gotten over it.
If you don't want to use chrome or chromium to run one single app to have proper encryption on your desktop in addition to your mobile device - which doesn't need a browser at all, and as a result of that "aversion" would prefer your messages are kept in clear text on a server your aversion is not worth considering further.
Or I'm wrong, what's the aversion that is more important than having your messages stored in clear text by a third party?
