The load of money they have moving contains quite a few secrets which together make everything, very, very unpredictable. They tell us one thing and do other. Call me paranoid, but keep an eye out for any low-profit services that you use because you never really know when they are going to be shut down. Whether a huge company running it or not.
I don't really own anything to be proud of except the content on my HDD and if I live long enough to be able to write a will, that little thing will definitely come with me to the grave. I can't trust someone / anyone getting hands on that. However, there is a chance that if someone get's paranoid about it, he'll dig me out.. darn this world I say!
As long as native support is still there, we have nothing to worry about and I seriously doubt that they'd be doing something like Microsoft and Silverlight.
