That sounds exactly like what I'd expect from a liberal professor of ethics. To add to the "consumerism is liberalism", it's not just about the media they consume, but the whole "vote with your wallet" thing. Consume the right products and we will have utopia eventually.
Yes, he makes several "vote with your wallet" arguments across the books but they're never too prominent.
Ethics in the real world is Singers worst book, its literally just various columns he wrote for newspapers and magazines collated into one volume. I've read some of his other work where while I don't agree with everything he at least puts it across far better. Most libs tend to hate him too because he takes a lot of viewpoints to a logical endpoint up to and including advocating infanticide and they don't like having to realise what their views result in.
