The idea that they're created for profit and therefore suspect remains conspiritorial nonsense.
I agree. But, being clear about the fact that Moderna made a huge chunk of change off vaccines is important.
It is also important to note that they'd been working on the technology for a dozen years, generally at losses from the millions to tens or hundreds of millions, to have the technology available to do what they did for covid. If we consider the net income of the company over that dozen years together, it is still a win, but not nearly so stunning.
If they were not allowed to make a profit now, those hundreds of millions to billions in net losses wouldn't get repaid.
We don't expect any individual here to do their professional work for nothing, so why do we expect companies to do so?
