Does Kingsoft Office Official PPA exist?

So, does Kingsoft Office Official PPA exist?

No. You need to download the debian installer file each time. WPS does not have an update feature. And since it is closed software it will not end up in the repositories since their license is in violation of any of the values Ubuntu stands for.

Please read LICENSE AGREEMENT OF KINGSOFT OFFICE FOR LINUX COMMUNITY VERSION (also called WPS OFFICE FOR COMMUNITY VERSION) thoroughly.

Their license claims you can repack it but several other restrictions make it impossible for anyone to make a PPA: for one how are you going to prevent a North American to download from your PPA?
