I know a little about the inside of the jira sausage factory from second hand reports. It's got the "accrete everyone else's business processes" problem that you mentioned, but it's also got the problem that it's quite spaghetti on the inside as well, probably for the usual reason - startup founders writing lots of code in a hurry and conflating the purpose of the software with its architecture due to being too close to the problem. Compound that with the usual startup-in-growth problem of more people than necessary (with presumably very uneven capabilities) working on the codebase and you've got a recipe for a maintenance problem. I do know that getting put in the jira team is one of the least fun parts of working for atlassian.
