So you're assuming game devs write every line of code in their server infrastructure. First, could be using a third party library you have license to use on a limited number of machines that make up your backend servers. Second you could be paying for third party API access to something like snowflake.

You either have to rip out the code (which may or may not break the server, but still requires developer time to do) or write replacement code which likely takes even more dev time to do or you would have done it instead of paying for the library/access to the service.
