[$] Free software's not-so-eXZellent adventure

A common theme in early-days anti-Linux FUD was that, since anybody cancontribute to the code, it cannot be trusted. Over two decades later, onerarely hears that line anymore; experience has shown that free-softwarecommunities are not prone to shipping overtly hostile code. But, as the backdooring of XZ has reminded us, theembedding of malicious code is, unfortunately, not limited to theproprietary realm. Our community will be busy analyzing this incident forsome time to come, but clear conclusions may be hard to come by.
