There might be a negative impact on some and a positive impact on others. If I'm a small business and I'm able to get access to work product information, say I'm a real estate broker and I want to grow my business, I want to know where the houses have been selling in Toronto or Victoria or somewhere else, and I might be able to build my business. Maybe someone else will be selling fewer houses because I'm selling more.
There are always some negative consequences, but these are the consequences that you would expect in a competitive economy.
