"I have not accused BlackBerry of directly paying for these fake reviews - I consider it extremely unlikely that they would."
No you have not. Unfortunately the commentariat who spread the news decided to tell a different story and chose headlines implying BB was faking reviews. Of course the trolls followed suit in the comments sections... which has become a form of sport regarding anything BB. These fine people are going to lose their favorite pastime when BlackBerry will be dead & done (they'll have to find another target).
I know BB is largely responsible for their precarious predicament; they have no one to blame but themselves. I am nevertheless taken aback by the vehemence and tenacity of their detractors... it's as if they cannot have peace unless BB is gone for good, and not soon enough. In Nature, turning on the weak is instinct... it looks like people are the same.
BBM is their last chance. Making it available on Android and iOS will encourage corporate IT managers to make BBM their default communications tool. The Delivered and Read status is important when it comes to business, especially in situations of crisis management when you absolutely need to know if the other person actually read the message. This in turn could stop BES customers from abandoning BlackBerry altogether and maybe encourage new customers to use BB's new Cloud based MDM solutions... and maybe buy a few devices. In this scenario there could be several hundred million BB users. BBM channels could capitalize on this to rival Twitter.
" If they're smart they'll concentrate on the developing markets where they're popular."
In Indonesia, BBM Money allows BlackBerry users to create a mobile money account attached to their BBM identity, and use that to transfer money to other BBM contacts, as well as purchase airtime credit for their device, or move money to bank accounts. The mobile payments allows Indonesian BBM customers to quickly conduct business transactions right in the service where many of them already communicate on business matters, and allow merchants and others to quickly accept payments with the devices they already own without requiring the involvement of any third-party device or software.
BBM for Android and iOS ensures these services and infrastructure will survive in the event BB10 sales continue to decline at the hands of cheaper Android devices. If BlackBerry expands this service to other countries it will turn BBM into a decent profit center.
To pull this off BlackBerry needs the right buyer. A buyer with a vision and a competent and experienced team of executives.
