I'm sure the MS lawyers thought long and hard about this and are patiently awaiting any actual lawsuits with confidence in their position. It would be very hard to prove ownership of any snippets. To the point where you can argue that it is just fair use and to the point where companies would think long and hard before committing any resources to fighting MS on this in court at great expense.
I don't think that will happen but it might be interesting if it did.
