Palantir uses stock purchase offer to keep former employees on tight leash

Full Disclosure: I'm a former employee of Palantir.

I'm not sure if I'm the only one, but the first story written by Alden had meat and data to it (although with heavy spin in a certain light). However, all these follow up pieces are weak and have no substance. Does anyone else feel he's doing himself a disservice by detracting from the original piece with these followups?

I have read Palantir's wiki page and browsed their website and am still not sure what is that they do !
