Of course, VPN is just a part of it, and I could not be bothered on a site like this of course as I am logged in What the VPN provides is of course save you from the prying eyes of others on the way to your VPN endpoint, but from there you are pretty much the same as anyone else, trackable back to the exit node which is the same for proxies.
Certificates provides a secure transmission as long as it has not been compromised.
Here however, the answer was related to if anyone asked me about my usage, and that question I will not answer when addressed by strangers.
This vm is only accessing this site and so is strictly club.myce.com related. then I have another one if I HAVE to access social media which happens once or twice a year (that vm is in other words used only once or twice a year)... a total of 28 installs for various work currently, of which none shares clipboard or supports drag and drop, some VPNed, some proxified, some like this one, not at all... Even reports everything I do to microsoft and is on full update auto as I would like Microsoft to get what I write in here.
My control center on the other hand does not leak anything as outbound default rule is block, not even a bit telemetry data, no Windows update, no nothing, currently even lacks a default gateway as I moved TeamViewer to a vm.
You are right of course, the question is only how much and what data and not online means none. We can do much about the amount, but none... as long as you're online, hardly possible.
