And even if they do understand you, in most cases their perception of you is as someone really paranoid about privacy, and yes they will undoubtly ask things like: "so you don't have twitter, facebook, instagram, ...". It's really hard to convince people or at least make them truly see all these dark things going on behind the scenes.
Regular people won't even talk about this, they don't/won't care. As long as they still able to see the content they are requesting this is something that do not affect them, it affects the people that know the shit is going on under the hood because we understand how machiavelic a move like this is.
On the other side if this somehow manages to ever see the light of the day, it's a huge opportunity for other people to come up with alternatives that effectively fight back this initiative and/or bypass it. If there's something that we do not run out of in this industry is creativity, for all sort of things, even the craziest ones, and that's something no corporation will ever be able to mitigate.
Also keep in mind that no browser is going to ever be in the podium eternally. Chrome has a expiry date, we just don't know when it will expire.
