Section 7.1 grants Arduino a perpetual, irrevocable license over anything you upload. Your code, projects, forum posts, and comments all fall under this. This remains in effect even after you delete your account. Arduino retains rights to your content indefinitely.

The license is also royalty-free and sublicensable. Arduino can use your content however they want, distribute it, modify it, and even sublicense it to others.

Holy shit the title doesn't cover it by half. This is beyond disappointing enshitification, it's a red light for any future use of Arduino.
