@Carl D - Same for me
Yes, Google might still be able to track me via cellular network but since I'm not using Internet on my phone, they have no way to push the advertising on me. At least for the moment!
Also, on my computer, I use Gmail exclusively in a different standalone browser so all that's left for them to push ads on me is search (where I can ignore them) and YouTube where they are so annoying that I swear to never buy whatever they're advertising. In the end, since I'm not purchasing anything over the Internet the data they collect is pretty useless so I guess those companies putting the ads are being robbed of their money since they can't really reach me.
I know there are ad-blockers I could use but I'm honest and if a site is ticking me off with aggressive ads, I quit right away and never go back.
