Providing the internet to someone who uses it for lawful and unlawful purposes

Q: What is the ruling on providing the internet to someone who uses it for lawful and unlawful purposes, given that some liken it to renting a house for a disobedient Muslim or an infidel? Is this true? What is the response to this comparison? Is there any doubt about the matter? Please clarify, as the matter concerns my parents.
