As I posted in the sibling comment, the Goals submission is at [1]. The Reddit and HN threads are pretty easy to search for (and there were quite a few). Summary, as I remember it, a group of primarily FAANG, with a large Google presence, authored a submission for the C++ Committee which was effectively a flag in the sand saying they (and their very deep pockets) wanted C++ to be primarily gear toward large, modern style development at large company scale. Removal of backwards comparability, limiting standard to only 64 bit architecture, preference for unstable ABI and language standard, etc. The document acknowledges that the use case they want the committee to push C++ towards is not for everyone, primarily because they all represent large money/scale interests, but they want the committee to go there way anyway.
