Looking at the C&D letter, it seems that Zillow is saying any use of their site for commercial use is prohibited. Wouldn't that cover traditional print journalists doing a similar story, or any story that made use of information gleaned from Zillow?
Why didn't Bloomberg receive a C&D for this story which says "Bloomberg used data from the U.S. Census Bureau, Zillow Group Inc. and Bankrate.com to quantify how much more money millennials would need to earn each year to afford a home in the largest U.S. cities." http://www.bloomberg.com/news/articles/2015-06-08/these-are-...
I guess nobody except the EFF really wants to take on this type of fight.
[a] Journalists using Zillow's site would likely be viewed as personal or editorial use, not commercial use.
[b] Bloomberg probably worked with Zillow.
[c] I'm not sure EFF would be interested in this. It's pretty standard TOS language, and when EFF did get involved in the Craigslist/Padmapper case, it was (correctly) interested in stomping on idiotic CFAA theories of liability and the exclusive license point. If Zillow tried to strongarm journalists, that would be a different story, but they have not done so as far as I know.
Background: I was a journalist before founding https://recent.io/ and would often get approached by companies like Zillow to write about what their data showed.
