PowerPoint templates go beyond page 1.
I am sure Skype's template is OK, the default colors are probably not set in such a way that they are easy to use for people without a degree (or passion) in graphics design. Like in almost all corporate PowerPoint templates, too much screen real estate is devoted to the brand/logo. With its strong blue colors Skype could actually afford not having a logo at all on its presentation pages. People will recognize the company regardless.
