- I use it to block ads. This way you don't need another extension in your browser (which often can read all data on any website you are visiting).
- Also you block any ads and any pictures or scripts of ads for ALL programs (Mail, Other Browsers) you use, not just your add on augmented primary browser.
- Trojans, malware etc. can NOT communicate home without you knowing it.
- You block certain countries from all communication (Russia, China, etc.)
- You learn a lot about which data goes where
- You learn and know where your colleagues are working (or slacking). This works at least for MS Teams when you do a phone or video call.
These are just a few examples.
