I read it and it made me smile a bit.
There are photographers who clearly abuse the tourist visa and they are getting caught. 5-10 trips to Cuba(or another country) per year is a clear indication for the immigration officers that the photographer in question is not a "tourist" as most indicate on arrival.
I don't want to go into details,but the info from this photographer is not full or correct. It looks more like an attempt to blame everything on the Cuban officials and make them the "bad guys" instead.
There are ways to photograph weddings legally in Cuba...most photographers just never bother to look into it.
Cheers
