FUD? Do you even know what FUD is?
Fear, uncertainty, doubt. Here. Let me look that up for you in Wikipedia:
http://en.wikipedia.org/wiki/Fear,_uncertainty_and_doubt
In case you're a TL;DR type, here's a relevant quote:
An individual firm, for example, might use FUD to invite unfavorable opinions and speculation about a competitor's product; to increase the general estimation of switching costs among current customers; or to maintain leverage over a current business partner who could potentially become a rival.
Let's go through that sentence clause by clause:
"... might use FUD to invite unfavorable opinions and speculation about a competitors product; ..."
Have you noticed the Microsoft ads hyping Surface and its so-called productivity features while depicting iPad as a leisure-time-only "media tablet"? Holding back Office or iOS is part of that strategy.
Now lets go back to the original post and the quote from the Microsoft executive. He said
"When they (customers) want to do real work, they are going to want to use Office." The original post also states
"We have some pretty exciting plans," said John Case, the top Office marketing executive, without giving any details.
The longer Office for iOS is held back, the more doubt Microsoft creates around iPad (and iPhone) and their ability to do "real work." Especially since MS executives have given no time frame for Office for iOS release. Or so Microsoft hopes. Which leads us to ...
"... to increase the general estimation of switching costs among current customers; ...
Without Office for iPad, businesses using iPads would need to switch to Quip and other apps that are available on iPad and other platforms. (This is in the original post, in case you didn't read it.) That means re-training employees, forcing clients and others to re-send documents in Quip format, and other possibly time-consuming inconveniences.
Holding back Office for iOS will, in Microsoft's eyes, slow down Apple's penetration of the corporate IT market. And it will raise fears of unknown switching costs. But Apple is steadily gaining installed base in corporations. They are displacing Microsoft in the Post-PC era. Which brings us to...
... or to maintain leverage over a current business partner who could potentially become a rival.
I'd say Apple is already a rival. Releasing Office for iOS would make them an even more powerful rival. Office for iOS would generate roughly $2.5 billion per year for Microsoft according to the original post's author. But it would be one of the final nails in the coffin of Microsoft's attempts to be relevant in the mobile space, if not the final nail. It would kill off Surface more or less instantly.
Anyway, as I said in my reply to the original post, FUD doesn't work unless you're a dominant player. MS isn't a dominant player in mobile, so none of their FUD in that space has much of an effect. On anyone.
Any more questions?
