The Hill has this list of the top 10 lobbying victories of 2016. FOIA Reform bill is among the top 10. The article lists the organization that are winners with the bill's passage but declines to name the one organization that spearheaded the bill which is OpentheGovernment.org. OTG worked very hard on the bill for a number of years and should get recognition for this effort.
FYI - since its passing over 50 years ago, the FOIA is amended about every 10 years. The crystal ball says the next FOIA reform will again start to perk up in about 2020-22, and pass in 2024-26.
