Where I work we're hosting our own gitlab instance and the previous company I worked for hosted their own Bitbucket. For most developers I know it's either a self hosted git platform instance or Github enterprise.
Github pricing is aimed at US companies. Small EU companies that can only afford to pay their 5-6 developers 60K euro per year rather selfhost than pay GitHub.
EVERY other client I've ever worked with used their own gitforge or at least bitbucket...
