Doing an email client in a dying (but far from dead) market is quite alright. They even made loads of money ! The problem is how they would continue to make money - next year, the year after and 10 after that - what plan did they have in store? If all they had was "better mail app", then sure, as you summarised it, the writing was on the wall and selling while still being hot property was the best decision to take.
