Wetpixel members have been receiving notifications that their upcoming dive trips to the Galápagos Islands have been canceled.  There is an active thread in the forums with information posted from multiple sources that confirms trips are being canceled due to enforcement of permit regulations. 

Apparently, a specific diving permit is required in order to run dive charters inside the park.  It looks like the Galápagos National Park is beginning to enforce tourism regulations as there are numerous tourism operators who only possess land tourism permits, but also carry out dive tourism as well. Tour operators benefited from the ambiguity and lack of enforcement over the years and offered services they were not permitted to. Now, many tour operators have been stopped from offering this option.
