Let say person A wants everyone to be rich.
Person B plots a plan to make themself rich and everyone else poorer.
One can make an argument that any action by A is now a contradiction. If they work with B, it makes a lot of people poorer and not richer. If they work against B, B do not get rich.
However this is not a contradiction. If a company use training data in ways that reduce and harm other peoples ability to access information, like hiding attribution or misrepresenting the data and sources, people who advocate for free information can have a consistent view and also work against such use. It is not a shift. It is only a shift if we believe that copyright will be removed, works will be given to the public for free, and companies will no longer try to hide and protect creative works and information.
