That same seven year old page explains how every single one of those features can be disabled. Directly in the Chrome options or by using a non-Google search engine.
Hell, just create your own query string as your Google.com[.localcountry] and you can use Google for your default search while still not sending the RLZ string.
That's all before adding any privacy/content blockers.
So the question still stands, where's the proof that Chrome tracks you and reports what you do back to Google?
Rational people who don't have an agenda know it doesn't, if set up properly, even before adding extensions. As one of them, I'm not afraid that Chrome does secret "conspiracy theory" stuff. With uBlock Origin added using additional blacklists, Ghostery (yes, I know they're part of the advice industry, they're honest about it and their tracking is ethically opt-in), Referrer Control, and one of IxQuick, StartPage, or DuckDuckGo as my default search, I am quite satisfied that Chrome doesn't "track me around the web".
There are reasons I still prefer and use Firefox or Firefox-derived browsers as my "daily driver", a switch back to that browser family I made about 2 years ago after a half-decade of Chrome preferences. But some loony "Chrome spies on everything you do" conspiracy nonsense isn't any part of my reasons. And I still do use Chrome too, at least several times weekly, for certain things sites it does better.
Maybe when the crazed Mozillians finish screwing up FF beyond the ability of CTR and Status-4-Evar, I'll go back to Chrome, Chromium, ironically a Chromium-based non-sleazy (rules out Iron and Dragon/Chromodo) browser. By then, Moonchild may also have screwed up Pale Moon enough in his quixotic attempt to remove all Firefox compatibility, so that the Chrome family is the only viable choice.
But until then, while I'm using a Mozilla-based browser, I'm still not giving in to nor spreading the unsubstantiated nonsense that Chrome spies on everything you do.
By the way, out of the box, Firefox reports back all the same types of things as does Chrome without turning off its defaults. And neither browser is necessarily "being evil" - Many people like search suggestions, typo correction, Safe Search, predictive page load, and/or localized search.
I don't, many technologists and sophisticated users don't like and use them, but those are valuable services for the "typical web user". Which services obviously need "what is the user doing" data sent to the browser maker and/or partner service providers, in order to do such things.
Make the browser choice for reasons, not FUD.
