That's a great question as well.
Intellectual property and the private market are said to be the best mechanisms to advance science.
Consider, though, the Montreal Neurological Institute-Hospital, which decided to fully adopt open science to address rare diseases. The Structural Genomics Consortium did the same. From a researcher's standpoint, intellectual property protection has, above all, become a barrier to research and product breakthroughs.
Obviously, the business world disagrees, because the intellectual property regime is the best way to keep profit margins very high. When it comes to research, breakthroughs and the development of new products, however, intellectual property protections are an ever-growing barrier, a factor that isn't being taken into account.
In the first few months of the pandemic, everyone worked on the open science model, and the knowledge base grew in leaps and bounds. During a public health emergency, the proprietary science model does more to fuel parasitic behaviours and price gouging, and does not necessarily meet the current public health needs, as we have seen.
