I play this video game which is developed by a small company. This game is great but it does not allow online multiplayer, you must play with other people on the same console. Recently, I learned that it is possible to play the game online using a software developed by another company.
If I created a website to find other people using the software to play the game online, would it be legal to make money from:
- Ads on the site
- Premium user subscriptions
Even though the service I offer relies on software owned by third parties?
