I do try and minimise my exposure - it's not always possible to avoid the harvesting completely, I do what I can though.
Google, Facebook, & Twitter have never been used, Microsoft & Amazon are used in moderation, no 'smart' meter or listening / looking devices in the TV, fridge, toaster or kettle, seperate VLAN for visitors devices & CCTV is hardwired to a DVR with no network connection. All data transfer is by DVD-R (not RW)
No store or 'loyalty' cards, most purchases are in cash, my phones are running LineageOS with no googly services installed. Work stuff is primarily airgapped, some is Company VPN only - the devices cannot be interchanged.
And i've never picked up a USB stick from the street....
