It would be smart if it benefited him, but it didn't. They tried to storm the fighter meeting for exposure and for Fabia to try and get his name out there for supposedly telling off the UFC staff but that backfired and Diego got fired and no promotion wants to pick him up because of the bad press coming from him and Fabia. People are concerned about Diego's health and they think his manager/trainer is "batshit crazy". That was the overall reason that UFC used to cut him was over potential health issues since Fabia was bringing up issues with health records. It was the outburst at the fighter meeting that was the real reason, but the technical reason is health concerns brought up by Fabia his manager.
So if he is trolling all it did was get him fired and preventing him from working. Since he makes his money fighting he just eliminated any way for him to make money. They got press but bad press, so Diego has no job and they are being viewed as crazy. Fabia isn't going to gain more students to train from all this. So nothing they are doing is benefiting them at all, it's actually the exact opposite. So if genius is what you want to call all this, that's your opinion.
