Because Akamai is substantially more than a CDN (arguably, CDN is now a smaller – albeit not small – part of their business): it is also certificate management, WAF, web app/API protection, IAM, edge DNS, edge workers, complex CDN rules, analytics and a whole bunch of other stuff.

Enterprise customers also typically and mostly use Akamai in non-CDN scenarios so they will have a hard time migrating off it if a need be, especially if they have invested heavily in Akamai.
