First off, the PS2 backwards compatibility was a feature of physical chips that was in some units and not others, and never got disabled by anything afaik.
But as to how Sony will handle indie devs. I view it as a situation similar to Apple. They are very hostile to the end user having root control over devices, but they are perfectly happy to allow any kind of indie games onto the platform. I don't think there is any risk of the sandboxed games going away.
