For the past two years, we have been concerned that medical practice and pandemic management have been skewed by selective hyperskepticism and bias. Dr Campbell speaks out, based on the recent paper:
We can look at a screen shot, where he targets domination of medical drug approvals by big pharma:

Earlier, he expressed concern about how integrity of the science could be compromised, as is now exposed due to Freedom of Information requests:

The obvious issue of special interest agendas leads to the issue of regulatory capture. Wikipedia (an example itself of ideological agenda capture) outlines:
In politics, regulatory capture (also agency capture and client politics) is a form of corruption of authority that occurs when a political entity, policymaker, or regulator is co-opted to serve the commercial, ideological, or political interests of a minor constituency, such as a particular geographic area, industry, profession, or ideological group When regulatory capture occurs, a special interest is prioritized over the general interests of the public, leading to a net loss for society. The theory of client politics is related to that of rent-seeking and political failure; client politics “occurs when most or all of the benefits of a program go to some single, reasonably small interest (e.g., industry, profession, or locality) but most or all of the costs will be borne by a large number of people (for example, all taxpayers)”.
Such capture will distort the market, scientific research connected to medicine, the practice of medicine, medical and general education, the media and more. So, it is a particularly pernicious and often subtle form of corruption.
More broadly, this also means that we cannot blindly or naively trust the official line and its claims regarding best medical practice. Hence, some of the controversies surrounding Ivermectin etc, repurposed drugs that are known to be safe enough and which because of evidence of various kinds have been used to treat other ailments than what such were originally approved for. In the case of Ivermectin, we now know or should know that contrasting population level results in Uttar Pradesh vs Israel, the UK and the US show that it is indeed successful in treating Covid-19.
As there was a needless controversy over what was being used in that 240+ million population state, we may examine a snapshot of a home kit:

We may broaden our concerns yet further. For, if there is a breakdown of integrity for something so manifestly vital as medicine, we can take it to the bank that the rot has spread far and wide: ideologies, interests, dirty money, activism and agendas are unduly affecting what we think we know or imagine is wise, good or advisable, on any number of subjects.
Arguably, that includes on study of origins.
We must return to first principles and duties of reason, to begin to reform and restructure knowledge, thus how we make and carry forward key decisions as individuals, in families, groups, organisations and communities. That’s hard to do and will be fought by those with undue influence, but it needs to be done. END
