Of course licenses are for the user! Without a license, copyright law forbids you from downloading and running an application, let alone copying it to your other PC or emailing a copy to your friend. Addressing copyright law doesn't makes licenses longer, it makes them exist in the first place.
It's true that the GPL talks about some additional things like access to the source and the right to modify it, which ordinary, non-programmer users don't care about. But you also need it, or some license, to use the software at all. The BSD one is much simpler, but it's still a license and still needed.
Networked services don't fall under copyright law, but other laws exist that prohibit accessing a service (if it requires authentication) except under such terms as the service provider offers to you in a license or other contract.
Another example: when you edit a Wikipedia page, you are presented with this text:
> By saving changes, you agree to the Terms of Use, and you irrevocably agree to release your contribution under the CC BY-SA 3.0 License and the GFDL. You agree that a hyperlink or URL is sufficient attribution under the Creative Commons license.
The linked Terms of Use, CC BY-SA, and GFDL contain many thousands of words combined, and require a grounding in copyright law to fully understand. Very few people ever give informed consent when editing Wikipedia.
> the higher standard of informed consent should be used before collecting any data
The Wikipedia article about informed consent says:
> Capacity pertains to the ability of the subject to both understand the information provided and form a reasonable judgment based on the potential consequences of his/her decision.
Most of the people in the world, and a significant part of the population even in Western countries, won't be able to understand the potential consequences of sharing their data.
I can't be sure I fully understand them myself! Twelve years ago, when Gmail was opened, I didn't know de-anonymization of large datasets would prove to be so easy. I didn't imagine Internet mobs doxxing and swatting people. What might be possible ten years from now with the personal data I share today?
If the law puts the burden of verifying the user's understanding on the service - meaning they can't trust the user's assurances - the service would need to administer an exam or interview to each prospective user. And indeed Wikipedia says to get informed consent, "the investigators must ensure that subjects have adequate comprehension of the information provided [....] assessing the level of understanding during the meeting". Obviously this isn't practical for Internet services.
The biggest source of personal data Facebook gathers is what its users post themselves. This would be true even if they didn't gather anything from Whatsapp messages, tracking cookies, etc. So should any services letting users post often-private content, like blogs and image hosters, require "informed consent"? That's just not practical.
I agree there's a problem. I don't see a solution yet. Banning everything until there's a solution is neither practical nor desireable.
