It's not the intent I perceive either, and the question here is intent, not
result.

Uh.... they intend the result, even if they don't intend the result.

That is to say (before somebody quotes this as the mark of a moron - I
may be a moron but that's not my mark...) they intend to dominate the
desktop and obliterate the competition. They don't care how they do it.
They may =intend= to do so by co-opting the file formats and making
people who don't use Microsoft Products not fare well (e.g. those who
program Java will tend to use the Microsoft extensions because they are
common though nonstandard, but they won't show up in competing
platforms, but who cares - there aren't enough of them...)

This has the intended effect of causing people to buy Microsoft products
(they sort of have to) and the unintended effect of making Microsoft
appear superior (because nonstandard but common stuff works with
Microsoft but not the competing =standard= platforms)

Microsoft likes the unintended effect.

There is plausible deniability.
