It's funny how you only talk about sonys obligations but not how you agreed to their TOS:
- LICENSE GRANT Subject to the terms and conditions of this Agreement, all System Software is licensed to users solely for personal, non-commercial use on the PS3™ system in the country in which the PS3™ system was designed by SCE to operate. To the extent permitted by applicable law, your rights to use or access the current version of the System Software will cease upon installation of a newer version of the System Software onto your PS3™ system, whether such installation occurs through manual or automatic download by SCE through SCE's online network, or otherwise. SCE does not grant any license to System Software obtained by users in any manner other than through SCE's authorized distribution methods. Your use or access to open source software or freeware included with the System Software is subject to additional terms and conditions set forth in the instruction manual or documentation for the PS3™ system or at http://www.scei.co.jp/ps3-license/index.html. Such additional terms are hereby incorporated by reference. You do not have any ownership rights or interests in the System Software. All intellectual property rights therein belong to SCE and its licensors, and all use or access to such System Software shall be subject to the terms of this Agreement and all applicable copyright and intellectual property laws. Except as expressly granted in this Agreement, SCE and its licensors reserve all rights, interests and remedies.
Also if Asus (or Microsoft) decided to stop support for Excel within their current Office version, you can do shit about it, since (just like with SONY) you already agreed to their TOS.
Blindly agreeing to any TOS is your own fucking fault. Think before you talk out of your ass.
