What you're left is a company with 8000 employees and a system to problematic to change.
With the recession incoming, the time for free money is over and tech startups are bound for a correction. I'd sell or get ready to wait 10-20 years.
Even in the wait scenario, you're basically hoping that a huge corporation will transform itself and rediscover their startup roots - which is not likely to happen.
It happened with Mashape (sold their unprofitable marketplace to the RapidAPI people - geez, what a bad deal, it was painful to watch) and they managed to reinvent themselves with Kong.
They literally did a bunch of experiments and went on with what succeeded, ignoring their main, flawed, business model.
That's what companies should do to chase success, they need to act like venture incubator, don't bother their teams with corporate BS and hope one of their teams will succeed. If they behave like mammoth corporations they're doomed to fail.
