Yeah, it seems that quite often celebrities will speak up about a problem they've had, urge people to check for signs, describe what happened, or even become an a voice to bring attention to a cause.
Seems strange that Jamie Foxx wants to essentially do the publicity (releasing videos and photos) but not any of the public service stuff.
I wonder if he had a reaction to a prescription drug that has embarrassing side effects and doesn't want to be associated with whatever they were.
