In my opinion, this is not a good thing.
I just updated movabletype-plugin-core to 4.3.2-1 and now see an unrequested and unwanted Zemanta plugin. What's worse is that when I try to disable it, nothing happens!
Debian - I'm filing a bug:
After upgrading to 4.3.2-1 a new window appears: Zemanta Content Recommendations. There is apparently a bug which prevents this plugin from getting disabled, but I also have a problem with something getting installed on my server which accesses the remote networks without my permission.
Hah. I just noticed a typo, but its kind of funny!
"which access the remote networks..."
UPDATE: For some reason, the disable button now works. I'll have to update the bug if it is accepted.
