I agree with your friend. If it's not straight enough to suit you, you will need to stake it. I doubt he did any serious damage since it still looks fine and is only slightly leaning.

The Fruitnut

Moles are after grubs there food sourse are insects. Grubs are feeding this time year on roots plants grass mostly there food sourse. Your lawn looks to be stress by grubs are drought. If grubs milky spores is best control. Pocket gofers do this same sign if after roots of your plants it look like mole trail but be short distance.

We don't have Japanese beetles here. We do have lots of summer drought. Not sure I've ever seen a long-established fig tree with a bolt upright main stem. Many are forking as well, with multiple trunks. However, if the one tree is leaning markedly during a short span of time root deformities due to careless container culture is the common cause of this in nursery stock. Entire tree could go over in wind or snow at some point in future, if problem is severe enough, or even start girdling itself later.

Low bushes in particular appear in these shots to be on the yellowish side. Your soil may be low in nitrogen and/or perhaps something else, like calcium or magnesium. In gardened soils in maritime areas nitrogen deficiency is the most frequent of the major nutrient deficiencies. (Some rainy outer coastal sites may also have a dearth of phosphorus).
