Stop acting so entitled!!!
Ubisoft EULA clearly states in section 1 Grant of License; "1.1 UBISOFT (or its licensors) grants You a non-exclusive, non-transferable, non-sublicensed, non-commercial and personal license to install and/or use the Product (in whole or in part) and any Product (the “License”), for such time until either You or UBISOFT terminates this EULA....THIS PRODUCT IS LICENSED TO YOU, NOT SOLD.".
Your use of the online account signifies your agreement with the EULA, Terms of Use and Ubisoft's Privacy Policy. All clearly stated in section 1 of the Terms of Use. With one sentence explicitly stating the terms of your online account use; "As a User, your use of any or all of our Services indicates your acceptance of these Terms and your agreement to comply with them fully. If You do not agree with these Terms, please do not continue to use our Services"
This is common to all software nowadays, it is licensed to you, you have zero ownership. Protected by copyright and other legal protections, you never did own the software. Nor does the software company have any legal obligation to maintain software in perpetuity. That people have signed the petition against Ubisoft's license and use agreements effectively terminates their license to play the game and use their online account.
