Why do so many tech companies seem to be releasing “secret sauce” for free lately? I see a lot of posts lately detailing how inner production systems work at large companies, and while I’m grateful, I’m curious why the higher ups think it’s worthwhile to release this information.

PTP isn’t secret sauce. Routers I worked on were doing PTP in like 2009. 1588 was standardized in 2002.

There was the TICTOC workgroup, PWE3 for psuedowires on MPLS and whole labyrinth of IEC standards not to mention closed ring optical network clock syncs from SONNET/SDH. I suppose its secret sauce for social media software.
