That sounds completely wrong
If you have a linux package you definately get plesk.
Your screenshot above even shows the linux package has plesk included. It also shows on a managed you don't get root access.
Managed servers are for people who don't want to mess with settings, but need the power of a dedicated setup.
Which is exactly what i want, similar to yourself, however it seems that they dont supply plesk on managed (on the managed in the screenshot plesk has a dash through it, whereas ticked in the unmanaged ones). - which doesnt make sense... You create all your sites via their dedicated 1and1 CP... created one just in the 1and1 cpanel....
