Yep. The Unofficial Patch does the same thing; removing or changing content that WORKS as intended isn't 'patching', it's modding. What's fucked up is changing the scripting on some events and objects. Even if you revert his changes with an esp or by editing his esm the SCRIPTS are still fucked. It would take some investigating and file extracting to fix his 'fixes' but why should anyone have to? What he did was spiteful.
There was some kind of restored content garbage he did that purposely reinstated Stormcloak dialogue to make them look like evil racists BUT he didn't restore the Imperial dialogue that made them look like power-hungry sociopaths. Again with the modding disguised as some kind of restoration.
