Minors don't have any rights? Boy, are you wrong. Better go back and do some research on that. The law doesn't give ownership of intellectual property to others solely because the creator of that property is a minor. It might give control when it comes to contracts, but not ownership.
We're not just talking about ignorance of the law. We're also talking about accessibility here. Poor people don't have the resources that corporations possess, yet we're requiring them to do activities that are properly placed on the corporations seeking to make a profit from their work. You better believe they are. Every time I use a search engine to look up something on the Internet, I'm exposed to advertising that was paid for by companies seeking to be seen on that search engine when it's used. They know that users are seeking the content that search engine can display. The search engine people have been smart enough to know that they could deliver more traffic if they could keep pages that might not be available any longer even though those pages might contain copyrighted material. That's going beyond fair use.
Consequently, search engines are using that copyrighted material without permission because the law permitts them to do so based on the idea that entities with intellectual property should know enough on how to opt out regardless of the fact that there might be a hundred such search engines that they're unaware of in existence. Well, that's not how the general public is. We've already seen plenty of examples where ordinary people didn't understand copyright and thought that anything placed on the web could be copied freely. This is a case where the law is ignoring other laws that have worked on the premise of what an ordinary person would know and understand. So, we're to just let that establish a new precedent?
What next, do we have to demand that the deceased contact mortuaries to let them know they're opposed to tissue harvesting because they didn't know when they were alive that they might be delivered to a mortuary that permits such practices? Yes, this is an extreme example, but it points the direction the entire opt out scenario is going.
Sorry, but I'm against opt out. The burden shouldn't be placed on those whom businesses are trying to make a profit from. If the business wants to use their property, regardless of what it is, then the burden should be upon the business to get the person to opt in. No business should have the right to make a profit on someone else's property and then be allowed to say, "Oh, you don't want us to use it? Well, okay." and then not pay for the use, however slight it was before ceasing their use.
