Wasn't that because Apple wants 30% off all sales? Microsoft had a similar clash with Apple over Office for iOS. The apps were free, but if you wanted to buy a license to use them, you would have to purchase that license directly from Microsoft because Apple wanted a slice of the upsell. This would have added a 30% tax on top of the universal service fee Microsoft was selling, even if it was just a link to the website from within the apps. I don't know how that was finally resolved, but this is just how Apple conducts business.
Guns do kill people. That's the whole point, and why I'm a 2nd amendment supporter. There is a fundamental right to self-defense. Any politician who disagrees is an incredible hypocrite, as they cavort from place to place with a cadre of armed bodyguards.
Nevermind that studies show a weak or non-existent link between banning guns and homicide reduction. But even if they didn't, the right to bear arms is more important than letting politicians decide who has the right to self-defense.
I'm ambivalent about the 2nd amendment (and in fact lean left on it) but flat-out blaming it for the state of personal safety in the US is the dumbest thing I have ever heard. "Guns don't kill people, people do" at least points to the important and relevant truth that murder and homicide is a human behavior with complex motives, even if that alone wouldn't be enough for me to support private gun ownership. "You're not safe in the US because of the second amendment" is just a stupid lie.
