It is the exact same for BlackBerry. We have been hearing and reading and watching streams of news that BlackBerry was on its knees and the axe was about to come down and finish it off any second for years now. Yet BlackBerry still continue, releasing a new BB10 phone and planning to release 3-4 new devices in the next year or so.
I can understand what you're saying, but....
If I had £10,000 to spend on shares, there is absolutely zero chance I'd buy any of Blackberry's. Would you?
In terms of financial health, even though Blackberry survives, the fact that it has failed to maintain what was once a good grasp on the market basically means it's dead to shareholders, and they're the guys who dictate whether a company lives or dies, not the customers. It'd take a miracle for Blackberry to come back strong now - it's possible, but the market has matured and Blackberry didn't capitalise on their early strength. Not surprising, given the marketing budgets of Google and Samsung, particularly.
