Even though I like JS/TS, I agree... not to mention that at even 10x the suggested amount for paid accounts, or even $1 per private repo per month, it still wouldn't be significant to any individual developer... More along the lines of thanks for the cup of coffee money as opposed to income money.

As suggested, I do think there should be room for grant funding, especially in the case of govts switching to open-source (LibreOffice, Linux, whatever) and open-source individuals and orgs can apply and granted each year dependent on actual use. Though, even then, govts should probably do more for funding, but I don't want a situation where the org just spends more money than they actually distribute for dev (looking at you Mozilla).
