Ubuntu enforces use of closed source PDF reader via Firefox plugin

Binary package hint: acroread

My issue is, that I only recently added acroread to my installed packages, becaue normally I do only use open source readers. I then had to find out that I now do not only have acroread as an additional option, but that I HAD to use it, because now all PDF documents in Firefox open within Firefox via the acroread plugin.

This is not acceptable. no other PDF reader enforces that and I consider this an intrusion into my open source environment. I therefore request that this plugin is not installed by default any more!
