If you want to edit this theme, out of luck?

I tried to search and found a bit ,

I wanted to try fakebook again and quickly remembered why I hadn’t before, ad conflicts

I need to make adjustments for it to work with native ads and other small incidentals

Any other solutions to work on existing themes that require specialty tweaks?

I see modifications are allowed in the license so is there any offense to download and remove the import settings, make it local?

Nope, that’s exactly what you should do.
