> For the record, neither service did; in fact, both tried to recruit me as a result of the visualizations. The difference is that I am not using the data to create a direct competitor that could cause them to lose business.

I do not understand that implication. How is providing bike share information creating a competitor? I can't run a bike sharing service.

Less a competitor, more a non-canonical source of information that they cannot manage.

If your offshoot were to misrepresent data, for example, then you would become a liability, even if you weren't making money.

Random tangent: your comment about unmanaged non-canonical misrepresented data reminds me of Zillow, who publish "facts" about real estate transactions, with no mechanism for error correction. Afrw years ago they posted an erroneous sale of my house -- which transaction never took place -- listing a sale price 20% lower than we'd paid for it. It directly harmed me, when we later tried to sell the house, when potential buyers cited zillow's "estimates" which of course were artificially, drastically lower because of the phantom transaction. There was no avenue for recourse; angry tweets got a half-baked response from a junior social media person, but it was never resolved. I wonder how many others zillow must have messed up.

That's a fair point. Easily enforceable by a proper license. One example is ETALAB open data license.
