Basically this is true for most startups in the world BUT Cursor, so here you are kinda inverting the logic of the matter. Cursor is at a size that, if they wanted to use K2.5, they could clearly state that it was K2.5 or get a license to avoid saying it.

In practice nothing happens after violating an open source licenses, especially if you are willing to follow the terms after being notified.
