This week, the Supreme Court is set to hear two landmark cases that could have a major impact on the internet as we know it.

The first case, Google v. Oracle, has been making its way through the courts for the past decade. At issue is the question of whether or not Google’s use of Oracle’s software code constitutes fair use under copyright law. The implications of this case could be far-reaching, with some experts saying it could upend the entire internet.

The second case, a family’s tragedy, involves the social media platform Facebook. The family of a deceased Marine sergeant is suing the company, alleging that its failure to adequately protect user data allowed the Marine’s murderer to find and target him. This case could set a precedent for how social media companies are held accountable for their users’ safety and privacy.

Finally, the Supreme Court is also considering a case that could have a major impact on the internet’s future. Google v. Hood involves a law in Mississippi that would allow state prosecutors to sue tech companies for providing user data to the federal government. If the court rules in favor of the state, it could set a powerful precedent for other states to follow and could throw the internet into chaos.

No matter the outcome of these cases, their impact on the internet and tech companies is sure to be far-reaching.
