It is "unsafe" for the would-be helper to help people who aren't asking/paying for help and who don't understand the difference between a easily changed default setting and installed spyware.

With such people, you never know when they will simultaneously accuse you of "breaking" their computer and remove your access to said computer so that whatever you've done that they believe "breaks" the computer indeed becomes "permanent" and is something they can be permanently pissed at you for.

Some people can't be helped. In such extreme cases with incredibly unreasonable and unknowledgeable people just don't upgrade their browser. Let them languish.

On the other hand it could be a benefit to be removed from the duty of maintaing their computer, so maybe pissing them off is a (selfish) win.
