That twitter thread (which is great, btw, everyone interested in this stuff should be following @greentheonly) doesn't remotely substantiate "Shadow Mode isn't real, and that Tesla is outright lying".
I don't know the extent of public statements about it, but comparing collected data like the stuff detailed there to driver behavior is certainly feasible and almost certainly being done. It's also likely true that the marketing department had their way with the announcement and made it sound more like an on-vehicle entity, but.. meh.
I just don't see how you got from that (again, really great) analysis to such an outraged conclusion.
