Nowadays games assets are just crazily huge. AAA games tends to ship at 50G. Now think about the raw assets size and saving all the intermediate revisions.

It's quite easy to burn 1000G of storage on GitHub/GitLab (again, don't forget all the revisions). That puts just the storage cost at $6000/year. At this price point, it's really worth hosting on your own.

As Danieru mentioned they are forcing ppl to manually do cleanups, that probably indicates the storage costs are even higher which worth manual interventions.
