Cochrane offers a trade-free service in the sense that they ‘provide reliable evidence that people can use to make more informed health decisions.’ and offer them freely: ‘Since 2013, we’ve made all Cochrane reviews freely available 12 months after publication and all protocols freely available immediately. Over 3 billion people worldwide have immediate access to all content through national access agreements and our free access offering to over 100 low- and middle-income countries.’

They also ‘do not accept commercial or conflicted funding. This is vital for us to generate authoritative and reliable information, working freely, unconstrained by commercial and financial interests’

However, they don’t publish everything immediately as free: https://www.cochrane.org/about-us/our-open-access-strategy

Therefore maybe 4/5 blocks can be given for this.
