Chromium is still controlled by Google. Exhibit A: this ad-blocking API issue, where Google decisions will affect all Chromium browsers. (Sure, they can maintain patches against upstream, but over time that becomes non-viable.)
If Google's behaviour concerns you, you need to use Firefox or Safari.
This is a strange comment. On Linux at least, Firefox is far easier and quicker to get building from scratch than Chromium. I've done both relatively recently.
