I agree that 2-3x is more appropriate. Either way, don't you think the maintainer of Babel could easily be making more money and doing easier work (individual contributor at some large org)?
The accusations that this person is freeloading off of Babel donations seem absurd (especially when you consider who is making them). The babel maintainer could be coasting at a large engineering organization with a lot less responsibility is what I am getting at it. It's exactly what the creator did...
The accusations are unjust.
