noun: hara-kiri, noun:harakiri

I strongly feel Blackberry committed hara-kiri by releasing BBM as a free app on both iOS and Google Play app stores. Correct me if I am wrong but the reason why 99.9% of people got a Blackberry phone was because of BBM  while the remaining 0.01% are the weirdo’s who got it for push email et.al. Blackberry phones are whack, battery life atrocious, their app store is filled with crappy applications.
Why did Blackberry give away their crown jewel (i.e. BBM)? to remain relevant in the mobile space? too late. Back in 2009, it would have been a stroke of genius.
Now that BBM is available for both iOS and Android, would any sane person actually go to a store to pick up a Blackberry phone? NO!!!
If the release of the iPhone dug the grave site for Blackberry and Android put her in a coffin, then the release of BBM just said the final rites and poured sand over the coffin in the grave.
Even if Blackberry wants to transition into a SAAS company and somehow charge for BBM via TELCO’s, would anyone actually pay to use BBM when whatsapp and its ilk are free?
1. The sole reason for my short lived romance with a Blackberry phone was basically because of BBM. I was tired of people asking me for my PIN. (covers face in shame).
