They’re using the broadest definition possible, where tax dollars are generally meant to provide public service.

But at that point you’re just in an argument over which public services are most important to whom.

So then implying that tax dollars should be used instead of donations is wrong.

From my understanding of USA as a foreigner, tax dollars are for corporate bailouts and military.

I agree with parent, the full quote is: "The whole thing relies on donations to keep it afloat, which is really what tax dollars are for."

I think this is a great site, love what they are doing, and support them (including a literal donation). But a government maintained website for this data is low on my list of things of what tax dollars are for. In fact, I think this is better done privately. To be clear, many of the things every US administration does including this one I also think is better done privately.
