Re "state actor", while reading the headline I figured "oh, they would have called it 'state actor' if it was believed to be Russian or Chinese", but reading the article, they may have chosen not to use that term also because it wasn't MIT but some loosely affiliated patriotic group. Given that the borders between state and non-state are very fluent in Turkey, there may also be multiple things being attributed.

Still very much possible that it's FUD/PR, there's likely information, misinformation, PR and news hyping in any such report, with degrees of each varying.
