Apple displays its new Code of Conduct on their WWDC registration page:
Apple is committed to diversity and to providing a harassment-free conference experience for everyone. All attendees have the right to a safe and welcoming environment regardless of gender, gender identity and expression, age, sexual orientation, disability, physical appearance, body size, race, ethnicity, religion, or any other attributes. In addition to treating others respectfully, please do not bring items with disrespectful, malicious, or sexually-oriented writing, images, or audio to the conference.
Apple reserves the right to refuse admittance to, or remove any person from WWDC (including from any WWDC events) at any time in its sole discretion with no refund, including but not limited to attendees behaving in an inappropriate, disorderly, disrespectful, or dangerous manner or failing to comply with these terms and conditions. All attendees must follow safety signage, instructions, and rules. If you have an experience that violates this code of conduct, visit Attendee Services and ask for a manager.
Refreshingly short, precise, clear, and no-nonsense. I’m just sad that these things have to even exist. They shouldn’t need to. We’re fundamentally all the same.
