Where did this one claim to not be based on Chromium? Homegrown can just mean "the UI and core behavior parts" not not using any third party libs (including rendering) at all.

They clearly sold it as their own rendering engine, not just a UI shell. Although I guess due to vague wording it wouldn't necessarily preclude being a fork of Blink.
