It could be possible, but what makes you suspect they're tracking cursor positions?

I'm not entirely sure how they do it, but I do know alot of information is relayed to websites that can be used to fingerprint and track you. Even if you aren't logged in they know where you are and what device you are using. Alot of this depends on how hardened the browser you are using is, because its entirely up to the browser to block this information.
You can try to confuse the data a bit with a VPN, but I'm not sure if a VPN alone counts for much these days.
If you really want no fingerprint you can try either of these two technologies:
TOR is a way to browse the internet that makes it very hard to fingerprint you. The network's bandwidth is limited and there are people in oppressive regimes who legitimately need this though, so I think it would be a waste to use it for regular browsing.
WHONIX is used by Edward Snowden himself. Its an OS within a virtual machine that is entirely reset everytime its run. It has alot of built-in privacy tools, but its not very convenient to use.
I personally use Brave with as many shield options on as possible, alongside a VPN when I think its necessary. On mobile I sometimes use Kiwi, which is unfortunately no longer available. Its the only browser I've found that actually masks whether your device is a phone or PC.
Private mode deletes cookies and browsing history on your device, it has no impact on the amount of information sent out to browsers and your ISP.
I love this sort of thing. Is there a group that specifically focuses on computing history?
It seems to specifically be looking at users who have gone on US government websites. Its not measuring all devices in the country.
What is that device? Its like a DS but with two joysticks? I love it.
The politicians and lobbyists should unencrypt their data first to show us how safe it is.
What is even the point of this research?
The normans were quite french by the time of William, so its a short term loss for a long term win.
Is it cross-platform?
It turns out they can and likely do track that sort of thing. Still, I highly doubt that's the only information they have access to.
