Yes! This video was what caused me to reconsider my use of Google services seriously.
I was wondering how to react if this happened to me while watching the video. If, like me, you use Google with your email on your own domain (eg. gsuite), you could, in an emergency, change your MX records to something non-google.
Worth noting that "In an emergency" also relies on your MX records' TTL being set to a low value
And the DNS not being managed by Google and the domain not being bought through Google.
