Change happens. You can adapt and seize the new opportunity, or if you are more risk-averse, wait it out and see how it matures. Any company can burn you at any point in time. How many services have Yahoo and Google killed off over the years (just to name two of the big guys)? Personally, I'm excited to see a company like Microsoft embrace the developer community (I can't wait to try Windows 10 on the R-Pi).
It's fine to have reservations about new technologies and companies' strategic shifts. Being a little skeptical is healthy. Objectively, you have to admit that there has been a massive sea change happening at MS over the past several years, and it's all moving if a common direction toward a more open embrace of the non-MS, open-source development community (I was as surprised as anybody when I saw that Azure supported non-Windows VMs, and I doubt they'll pull support for those).
While it's entirely possible (though I'd argue not very likely) that they could shift back to their old ways at some point, ask yourself this: Do you and the projects you work on stand to benefit from Microsoft's new direction? If so, you would be doing yourself a disservice not to try their products and services when you're ready. If they don't offer anything appealing to you, then what's there to worry about?
