I think the point is that the NSA allegedly infected air-gapped Iranian nuclear facilities (i.e. Stuxnet), so if they see you as a target they already have a trojan hiding on your phone (a much easier target than Iranian nuclear equipment) and transmitting your location directly to them, regardless of whether or not you enabled location history. Therefore if you are attempting to prevent government surveillance by turning off location history, you are wasting your effort and may as well turn it back on and enjoy the advantages. That said I don't believe in making their job easier, nor in giving out my info to non-government hackers nor to advertisers, so I have location history disabled.
