"Brian Vecci, technical evangelist at Varonis, 
  elaborated on what he saw as the downside of the
  zeal to crack down on data brokers.
  
  “Entire business models could be declared illegal
  and have to be scrapped if these complaints are 
  valid, and that might be a bad thing for 
  consumers,"

Sounds great to me. He has completely failed to show any real downside.
