Not exactly. 3.4 BTC received. Depending on when the donations were made it could be more or less than $73000.
Though it does look like he held ~1 BTC until Nov 2020 and then transferred it out. So it's possible he's actually received roughly the equivalent of $73000 USD from those donations
I was trying to check if my transaction went through, but then I started to wonder if I should fact check him on his claim that he didn’t have 80k usd to evade prison sentence.
But to answer your question - years of work for such a widely used project should be compensated more in my opinion. An engineer at google with similar skill will make 2-5x, maybe 10x as much.
