Sounds familiar, honestly. In my experience, you are looking at years of stagnation where the original platform keeps on running, nobody builds a decent successor, the customers start to slide away, and the whole thing just... shrinks. Eventually they sell it off to someone else or shut it down, but few people stick around long enough to see such ends. Instead, they'll churn new leaders and team members in and out every couple years. At each churn, some new group of poor souls will be excited for their attempt to revitalize it all. There will be a few people who stick around through it all, happy to just collect a paycheck from a job that doesn't truly require much work or success. But if you have any ambition at all, get off the sinking ship.
