Upgrade to free software license

[LorenzoAncora]

Hi DuckDuckGo Team,
you are currently using the CC BY-NC-SA license for this project.

The Free Software Foundation recommends that some Creative Commons licenses should be avoided. Hence, I suggest this project could benefit from transitioning to a free software license before your start further development stages.

For you comfort, a guide to ease this transition is already available here.

Best regards,
Lorenzo

I think they're using creative commons to be able to commercially license the data/system while allowing non-profit research use without charging

@HugoDF I don't think Lorenzo is saying they shouldn't use CC, he's saying that they should use CC BY-NC-*; GNU doesn't say don't use all CC licenses, they said the CC BY-ND and BY-NC because these don't count as free software licenses, according to their definitions. (too restrictive)

Lines 8 to 9 in 926b07b

	Licensed under the CCBY-NC-ND 4.0 license, (the "License");
	you may not use this file except in compliance with the License.

I wonder if it's a typo or not. LICENSE says this project is licensed under CC BY-NC-ND 4.0, while in README it's CC BY-NC-SA 4.0.

@Robot-DaneelOlivaw maybe they changed license a couple of times before publishing the work, creating this ambiguity. It should be corrected by the development team.

@JGHFunRun I left you a "like" but then you modified your message changing its original meaning and I only agreed with the original message. Please don't change the meaning of your comments after publication, it is not fair for your interlocutors.

Thanks @Robot-DaneelOlivaw for catching and reporting this! The correct license is CCBY-NC-SA 4.0 and we fixed it in #34 .
