But the web-scale demand for SCO Unix never really materialized. Linux took much of the marketshare while SCO went after IBM https://www.theregister.co.uk/2017/11/02/ibm_vs_sco_revives/
That wasn't the same SCO, the SCO that sued IBM was the Linux vendor Caldera who purchased SCO's assets and renamed themselves as such.
