This is a pretty clear case of SlideShare trying to grab too much. The LinkedIn 
API (which is their own proprietary thing, not OpenID Connect) does separate 
all the permissions into different scopes. However, the SlideShare app is 
asking for all of them, and LinkedIn doesn’t let you uncheck any boxes on the 
authorization screen. 

FWIW, the reason they want write access to your profile is to automatically add 
new SlideShare presentations that you upload to your LinkedIn profile page. You 
should still have the option of turning that off, or of turning on that 
functionality later.
