A million dollars please.

It’s called a copyright notice. Same as a license. If you’re running a commercial business you can’t legally just take that piece of work and reuse it. Pick any book off your shelf and pretty well every one of them will have words to the effect of:

All rights reserved. No part of this publication may be reproduced, distributed, or transmitted in any form or by any means, including photocopying, recording, or other electronic or mechanical methods, without the prior written permission of the publisher, except in the case of brief quotations embodied in critical reviews and certain other noncommercial uses permitted by copyright law. For permission requests, write to the publisher, addressed "Attention: Permissions Coordinator," at the address below.

Same as every piece of commercial software has a license which has to be abided by. Same as use of Meta’s service has terms and conditions which HAVE to be agreed to.

So yeah they’re free to break that license but they’re also free to be sued by IP holders for breaking it at scale.
