Thoughts on Code Obfuscation

I just wanted to get everyone’s thoughts on Code Obfuscation here for both themes an plugins? I bought a plugin and “developer” rights to it to use it on client sites, and I want to tweak it a bit to fit my workflow a little better, but when I opened the plugin files there is a bunch of gobbledygook in there.

Is it right for me to try to de-obfuscate it? And if it is, where would I go to even start learning how to do it. I don’t want to post the code publicly because I am not trying to share it or remove the protection or anything, I just want to make it work for me a bit better.

Thanks for your help.
