The summary is over-hyping this story, which is a day or two old, and not given anything like this much play in the mainstream media. The link to Forbes is actually just to a third-party renting space on the Forbes site, and the New Republic piece is opinion, not news coverage. Not that I am in any way denying or condoning Putin’s invasion, but overreacting doesn’t help.
You can (and should) use the LLVM/Clang static analyzer regardless of whether you compile with LLVM, GCC, or the hybrid of the two. During development, it’s sometimes worth experimenting with the compiler you’re not using, e.g. if you’re struggling with an error message. I’ve generally found LLVM’s diagnostics more useful, but sometimes a second opinion can be helpful, and Googling a GCC error message generally gets more hits.
