Hi Phil,
Sorry for the inconvenience caused by this issue. To send us a feedback, please go to http://g.microsoftonline.com/0O365COM11EN/135.
For this issue, if you still need to use Lync 2013 basic and Office 2010, when installing Lync 2013 basic, you can set the "Microsoft SharePoint Foundation Support" on “Not Available”. If you want to deploy the setting on several machines you can create a MSP file using the Office Customization Tool:
Configure feature installation states for Office 2013
