Kudos on upgrading your channel's name. There's a lot about computers that can make people lose confidence and when they learn there are solutions that can make them even more confident. It seems like the neighbor who owns the Wi-Fi router in this scenario was behaving as a bad actor. While he does have a good reason to enter his Wi-Fi password instead of letting the user do it, at no time should he have been doing something the owner didn't understand. There isn't much to going to the password prompt that anyone wouldn't be able to understand. I don't think he could have installed software without the laptop owner noticing, but if the person was an average Windows user and they use their Administrator account for everything (it kills me Microsoft doesn't do more to address this issue,) the guy with the Wi-Fi could have opened a text file on a USB drive connected to his router that contained a Power Shell prompt with the URI of the .dll folder on every Windows machine and made a quick paste in Power Shell to place a .dll on the user's machine. At which point Wi-Fi guy could effectively own that laptop being the ISP provider. I have allowed people to use my Wi-Fi and always tell them to navigate to the connection to my router and then the enter password prompt. I then enter the password and show them I am pressing enter. No one ever has, but if anyone was to ask why I didn't give them the password, I would just tell them it's just easier to trust people this way.
When your neighbor becomes your ISP.

If I am "providing" internet to someone else, how can i monitor which websites they are visiting ?
Get a router that allows you to log access, or fire up a tool like wireshark.
Use a halfway decent router that has the functionality. Sophos or pfSense would be great option here.
