I think that it's very easy to distrust large corporations, and lets face it we should know that it's easy for a company to lose track of things the larger they get. But google fixed Buzz as soon as complaints came in.
Now compare that with Microsoft who hide all their doings - code, formats, deals and who knows else under a veil of secrecy. We all know they have been disreputable about where they get some of their code from (at least in the early days).
I know who I'd sooner trust to be honest.
