This has become more of an issue with farmers over the past year, as they realize their data is a commodity just like what they raise--whether crops or livestock. How much of an issue? Two examples.
First, the Iowa Power Farming show was last week. One of the largest ag shows in the nation, and the back of the program had an advertisement from Ag Leader which started with the line: "Settling for a precision farming partner that wants control of your data just doesn't cut it." Additionally, several vendors in the precision ag and sensor/drone areas were stating similar lines. Whether BS or not, they wouldn't be saying it if there wasn't a need for them to.
Second, the January 17, 2015, edition of Iowa Farmer Today also addressed this issue in their editorial page article "Who own precision technology data?".
It's not that I'm against using technology for ag. It's I'm against others using my data about my farming operations AND MY LAND and making money off of it without cutting me in--or selling/providing it (raw or as a "derivative work") to other entities I may not want to have it.
