Yes and no.
Several bones to pick...
Jettison GMail: Alright, what he says is true, but it is also true of any online email service. Your ISP will give you an email for free, and while not guaranteed, as it depends upon the various privacy agreements as presented by respective services, generally speaking, your ISP will be less likely to be data mining.
Best to just treat all emails/texts like post cards, knowing that they are likely being recorded, and are generally not very private. If you have private information to transmit, write it in a text document, and zip that document inside a password protected container, mailing that as an attachment. .arj compression is the most secure... though for absolute privacy, use encryption software instead.
Switch Search Engines: YES - But again, any of the major search engines (Google, Bing, Yahoo, etc) are not much different. All are data mining. I will concur with his recommendation of StartPage, though I find it to be less useful for auxiliary features - I still use Yahoo for image searches, for instance.
Kill Chrome: YEP. Firefox, Opera, Brave.
Axe Android: Nope. I cry bullcrap. Now, what he says is certainly true of Google, but Apple is no better. Using Microsoft's front end over Android is no better. You are screwed. ANY smartphone is a data miner. tough sh*t, there it is. And of the big two, I would far rather have a droid than an apple, for cost alone, not to mention onboard storage, and better performance bang-for-buck.
Heave Home: ABSOLUTELY. But oddly enough, he doesn't even touch Microsoft Cortana, present and active on any Win10 machine. ANYTHING that requires an open mike is entirely muy malo, and that also includes Google Assistant or Siri on your phone. That being said, I have no open mike and no open cam on any machine in my house, but I DO use GA, because I can't see the dang phone well enough to use it otherwise. YMMV likewise. But be aware.
I can help shut off the telemetry to include Cortana on your computer. Inquire.
Clear cache and cookies: YES. I would recommend CCleaner for a one button mash that will clean all caches at once, rather than the method he gave. Inquire.
Pick a Proxy or VPN. Nah. Really rather ineffective other than where you have control of both ends... VPN between your laptop and your home for instance is a great way to stay connected to your home machine, but online VPN and Proxies really don't do so much.
