I feel like if you're technically savvy enough to have a good reason to be anonymous on the internet, you're hopefully technically savvy enough to not use incognito mode to do so.
There's plenty of reasons non-technically savvy may want to be anonymous:
* Don't want companies building a profile on them
* Writing under a pen name and don't want to accidentally link it to real name
* Researching a topic that might result in peers/society judging them badly
* Want to price shop without companies raising prices because of their browsing (I don't think this happens, but it's a common fear/accusation)
* Activists worried about being spied on
* Person with some suspicious looking connections who doesn't want that to reflect onto them (perhaps you have a cousin that joins a enemy of your country - you didn't do anything but just want to email your family about news without getting on a watch list)
* Doing illegal things and don't want to get caught
In fact I'm kind of struggling to think what reason for anonymity is unique to the technically savvy... pirating?
