Did you read the article that you linked? It appears that you did not. That article appears to contradict the quote. And the people that made that study that refuted that quote published their work in a journal that refuses money from pharmaceutical companies. Here is a link to their article:
Information from pharmaceutical companies and the quality, quantity, and cost of physicians' prescribing: a systematic review - PubMed
"Conclusions: With rare exceptions, studies of exposure to information provided directly by pharmaceutical companies have found associations with higher prescribing frequency, higher costs, or lower prescribing quality or have not found significant associations. We did not find evidence of net improvements in prescribing, but the available literature does not exclude the possibility that prescribing may sometimes be improved. Still, we recommend that practitioners follow the precautionary principle and thus avoid exposure to information from pharmaceutical companies. Please see later in the article for the Editors' Summary."
It is a potential problem. One that they are aware of and try to avoid, and it appears that to date they have been fairly successful.
You make it too easy when the refutation to your claim is included in your own links.
I present links, all throughout my website or on forums like this that will give the reader various sides of the story rather than providing only links that agree with my relatively uninformed opinion. I know that the Lancet has, in the past, published in their own pages, that the pharmaceutical corporations have completely taken them over, that they were no longer a science based magazine, I couldn't find it though. In the past I have followed links to the CDC and NIH that were removed after the alleged pandemic. They were hiding it, but you can go to the Internet Web Archive and those pages are preserved there. The Archive is being pressured to not do that, apparently.
