So right now when browsing the internet if you take no steps to protect your privacy, it’s like your house is surrounded by corporate spies collecting data on everything they can see you doing through the windows. And these are some huge windows.
Taking steps like adblocking, blocking known trackers, blocking third party cookies, VPN, and / or, blocking JavaScript altogether is basically just closing / blocking those windows to make it harder for the spies. Sure, they can still glean some info but significantly less.
With Chrome’s recent change, now you’ve been opted-in to having a tracker strapped to your chest. They promise the data is less exposing than the current data being collected, but that can change They claim it’ll protect your privacy because instead of the spies collecting data directly to provide to their employers they simply have to walk up to a terminal and collect the data the chest tracker has collected and curated.
This is just my interpretation, I haven’t thoroughly researched it I simply decided it was too much and moved back to Firefox as my primary browser after using Chrome for over a decade.
