I think your comment shows a misunderstanding of open source. Open source doesn't mean that a service is provided free of charge. You can just get the code, and that's it, no usability is implied. They absolutely don't pull the open source rug, in fact they are shining a light on how NOT open-source your Chromium experience was. I agree with one thing though: services are not to be trusted. They, or at least you, should have ways to migrate, as painlessly as possible.
