The @TwitterOSS got really hammered by the layoffs. They were real people, not just "high tier engineers". I take offense as some of my friends, real people, lost their jobs.
You shouldn't make light of other people's misfortune.
I had friends at Twitter OSS too and the ones I knew are pretty well poised to do whatever they want at this point. They definitely are high tier engineers.
It sucks, one of them got me my job, but they're going to be in pretty high demand.
