Why are collaborative services running on my end user's computer? What do we need a collaborative synchronizer background service running for?

We are a company that forbids the use of cloud based services for obvious security reasons. Downloading a PDF viewing app such as Adobe Acrobat does not warrant the installation of cloud based services that we did not sign up for.

We have begun using Foxit, because Adobe continues to ***** around with customers, thinking that we need this or that while installing it all automatically without the option to opt out of any of it..
