In 2009 @Forbes bought True/Slant and rid it unpromising contributors like Michael Hastings and me.

Today it summed up opposition to Palantir as due to intel links and - seriously - that it's "said to have helped find Osama bin Laden". https://www.forbes.com/sites/thomasbrewster/2020/04/11/palantir-the-peter-thiel-backed-20-billion-big-data-cruncher-scores-17-million-coronavirus-emergency-relief-deal/#357e38235ed1

"Despite the ostensibly controversy-free deal with the British health body, the reception was somewhat frosty. That was, in part, because of Palantir’s links to the U.S. military intelligence complex; it was funded by the CIA’s venture capital fund, In-Q-Tel..."

"...and was said to have helped find Osama bin Laden. The uneasiness from privacy bodies was also related to Palantir’s work with Immigration Customs Enforcement (ICE), which has drawn some criticism from human rights groups."

For a slightly more comprehensive summary of why Palantir has been stridently opposed since 2011 - long before it was caught in Cambridge Analytica elections scandals, lied about it, got caught lying, and then escaped scrutiny yet again - see this thread https://twitter.com/PursuanceProj/status/1247742832917409804
