Concerned that google has so much info ( https://myactivity.google.com/myactivity ) I visited https://myaccount.google.com/activitycontrols to turn off Web & App Activity, but left Voice & Audio Activity on. This breaks my google home. I do not want Google to save 20 years of search history so I can use a stupid google home. For the first time I'm considering Apple's device. This is a dark pattern Google
Also, most likely you turning off tracking will impact your Google experience.
Google is different than Facebook in that they offer real value services without which you can't survive a day on the web. Just count how many times you rely on a Google service in a day. The least you can do is to support them in maintaining their ad ecosystem in return. Or be ready to pay for their servuces. Unlike Facebook, Google has never had a data breach/trust issue.
