You're paying for an "if something goes wrong and it's the software's fault you can sue us" license
Of course, you can always sue. A $2T company. Good luck with that.
Would only add that the main reason people buy these licenses, apart from familiarity, is so they can shift the blame if something goes wrong. Its all about ass covering.
1) the illusion of "support" 2) OSS-fearing companies' love of indemnification
