Can’t help but think there might be a relationship between people complaining about paywalls and newspapers being bought by billionaires. We should be willing to pay for news because that’s how journalists get paid.

On the other hand, I'm 100% against paywalls in scientific journals. Research is almost entirely publicly funded, and scientists do all the work (have ideas, get money, research, write, review). Plus, we pay publication charges. All scientific journal articles should be open access.
