I see that Microsoft is now in talks to acquire Ustream.tv. This following their bid to acquire Yahoo.

From a purely selfish standpoint I sit here hoping that Microsoft doesn't cripple Flickr and Ustream for non-Microsoft browsers. Today these services seem to be platform agnostic.

I'm not an open source purist but I do tend to use FOSS whenever I have a choice. I just have to wonder if Microsoft will develop these tools ignoring the "10 percenters"?

Are you concerned?
