An interpretation of the word "reasonable" is literally all discussions of the 4th Amendment have ever come down to, you can't pretend like someone with a narrower scope or "reasonableness" is just haggling over semantics and nitpicking tiny details.
But those companies are both American, aren't they? Regardless, I feel like the ceiling for outrage and/or concern has reached its ceiling, at least among foreign governments who can at least do a semblance of something about it, since it's way more important which companies are used the most than the nations from which the companies in question originate, and the NSA has the data of all the most popular internet companies in the world.
It's not because we have more information, it's that THEY have a lot more information. The amount of our lives that we divulge to or involve the internet has shot up exponentially, certainly since the 1990s but when you think about it, even since, say 2000-2005.
Oh, right. Congress can repass it, but provided the Executive branch respects the function and decision of the judiciary, the Supreme Court does have the final say over congressional acts that have been challenged.
I've never understood the mentality that leads to homeschooling. When so many people are terrified at becoming parents/at being new parents because they've just been entrusted with a life and they're afraid to screw up, where do parents find the confidence in themselves to believe that they should be responsible for the totality of a child's exposure to other people and knowledge? At least a school experience allows for new ideas, experiences, role models, and environments.
E: Not to disrespect any parents who have decided to homeschool, of course. I was homeschooled before I was old enough to start preschool, and my brother was homeschooled for a year during, I think, middle school. It's a decision my own parents made, too, for a period.
A SCOTUS decision IS binding to Congress. They can't pass a law doing something that has been deemed unconstitutional unless they first amend the Constitution to explicitly allow them to do that same thing, which is obviously not going to happen.
