No, you contributed under the premise of the LICENSE that was active when you contributed _and the CLA they made you sign before they accepted your PR_, which said that they're allowed to change the license later on if they feel like it. If you think that the company changing the license for future versions is a middle finger, you shouldn't be contributing to projects that make you sign CLAs.

Sorry, I was responding directly to the claim ""once something is OSS, it has to be so forever". They owe you what exactly?" without thinking about Lightbend in particular. If you sign a CLA saying they can change the license later on if they so wishes, they are of course free to do so.
