Greatest Hits compilations can be released by whichever party holds the rights.
EMI released a 'best of' Radiohead album back in 2008 after Radiohead had chosen not to renew their contract after their 2003 album release. They were contracted to six albums and had recorded and released all six going back to 1993.
Radiohead couldn't do anything about it because EMI held all of the rights under the original contract. As it happens, they have made a lot more money as an independent band.
Twist in the tale is that Radiohead eventually (in 2016) managed to get their back catalogue signed over to XL Recordings (a label they've had dealings with for physical releases since 2007) and now they manage it. The 'best of' that EMI released has been removed from streaming services, etc. subsequently.
