I didn’t take the picture. And I don’t know if this person wasn’t compensated for this image.

The reason you can post all those images on the internet is almost entirely because of Section 230 of the Communications Act of 1934 or Title V of the Telecommunications Act of 1996. The law essentially provides website providers immunity from third-party content. Generally believed to be the basis for the internet as we know it today, it’s not a given that those protections will remain in place. Giants such as Facebook and Google are under scrutiny from lawmakers for antitrust violations and other misuses of power. No more Section 230, no more upload free-for-all. source

I’m aware of the concerns, but should every meme be copyrighted? Can I not take a photo of my daughter at Disney Land and post it to FaceSpace because unconsenting people are in the background?

Maybe the more pressing issue is to address the house less situation instead of berating people who copy paste images. But, that’s just me.
