I think that ship has largely sailed:
A computer detective on the police force suggested trying this with an iPhone:
My girlfriend and I started talking about sloths (a random topic that she has not texted or posted about) with her iPhone sitting nearby.
Sure enough, a day later she had lots of pictures of sloths popping up on her Facebook account. Aside from a sloth park in Costa Rica, there were no links to commercial products, just photos.

When I hold my iPhone, I can feel it vibrate for a short time. No idea why and I seriously doubt anyone will tell the truth, but I have to think it's sending info to some server for advertising because I see a lot of ads for things that I never searched for, only talked about or were mentioned by someone in person or on the radio.
There's a whole section about Siri & Search in the Settings menu. I just looked and it's enabled for a lot, in my phone.
Well, that was interesting- I turned off Siri and Search on the apps shown- took over fifteen minutes and after turning Siri off, a button for 'Show App' appears and needs to be turned off. Also, Contacts and a couple of others had a third button appear, which I turned off.
I guess this is what happens when we agree to the the EULA that's so long and filled with BS that we don't want to read it.
I think we need to tell the manufacturers NO! when they use the EULA to cover their asses so completely and if they want to make it impossible to use their products without it, we use something else. I'm not a conspiracy theorist, but the chances of our info being used against us, against our will or without our knowledge seem high, to me.
Investigations and government overreach is using all of the technology available to them.
WI had a John Doe investigation into the Republican Party's contributors, including FBI home invasions before daylight where kids and families were in the homes of people named in the investigation (which was illegal) and one of the people whose house was invaded is a Democrat, who didn't know he was being investigated until he happened to google his own e-mail address and saw the number of google searches for it (which should have been low ) and then, he looked into who was searching. He blew the whistle and the report in the link is the result-
