> On HN, I really expected better of people. Why does everybody think this is open source?
If you put five HN users in a room you will get at least a dozen definitions of "open source".
>Does everyone also think OpenAI is open source?
No one thinks that OpenAI is open source.
> Or a non-profit?
I think most people just assume that OpenAI is a for profit company (which it is). There is of course a non-profit foundation that is a majority shareholder in it.
> Does putting open in the name just mean you're going to love it?
Obviously not, since people here definitely see Meta as the good guy when compared to OpenAI.
