Curious how this impacts Streeteasy, which Zillow just bought some time in the past year. Streeteasy is the defacto MLS (in a sense) for NYC (Manhattan doesn't have an MLS, nor does Brooklyn. Uncertain about Staten Island, Queens or Bronx).
Streeteasy simply never had access to RLS so they had to get their data from other sources, primarily from scraping websites and emails, as well as some direct data feeds from brokerages that agreed to work with them.
