I could talk at length about this; unfortunately, I'm on my phone with a shotty connection.
The tl;dr is that companies like Snyk make money by requiring companies to pay to check for vulnerabilities once they've been downloaded. There's not necessarily anything wrong with that, but a philanthropic company could make things significantly safer for everyone if they weren't concerned about making money. Initiatives like the OSSF will hopefully have a positive impact, for this reason.
