Yes, by educating I mostly mean word of mouth. But also sharing of user friendly guides like PrivacyGuides. An alternative browser can only disrupt Google's control on the web by gaining significant market share, which requires convincing and converting users to the better software alternatives to Chromium. We must educate because we are the tech educated minority, and we require the assistance of the majority to oppose googles unilateral control. I think Gecko is a better option to put development time behind (or better yet Servo), or abandoning many of the privacy invasive web standards and creating a new internet (which of course would never see wide use).

TLDR: We need the majority to be more educated about tech or things will keep getting worse regardless of a new browser engine or anything else.
