Speck was pushed and provided by Google to linux, they added the content to the kernel having your naive belief, it was later found containing a backdoor to ALL systems, and Google raised their hands up and said it was passed to us by NSA. Is this what happened? Or did I dream all this up?

Facebook provided 0 FOSS, not a bit, suddenly they make an algorithm they "bought" including the author, and make it foss, to build it it needs google software, like a bush fire more than half of distributions adopt it and all data provided as comparative to xz are false, based on poor use of xz to make zstd appear better, while still admitting zstd can never attain the level of compression, but it is fast (ONLY when xz is run on a single thread while zstd is multithread by default). They claim xz sums are different when run on 1 cpu or many, still not true.

Just wait for that bomb to explode, the guy who wrote the code for zstd doesn't seem possible to have enough knowledge to write it, he appears as a front for something.

Things that smell like shit don't have to be actually tasted to be called shit.
