The tag info for manipulation reads:

The technique of disassembling two or more parts from one another.

and all existing questions are actually about this.

However the word manipulation has a much broader scope than this, which is suboptimal for two reasons:

• It may lead to people misusing the tag.
• People who want to search questions about disassembling Lego cannot find them, as they cannot find the tag.

I therefore suggest to rename this tag to disassembly, dismantling, or deconstruction (and make the others synonyms).
