But they didn't have this for completely different reasons. They invested money years ago, that they could've bought government bonds with and just earned interest, and instead it went into BlueSky. At some point they'd like a return that would substantially beat the government bond they could've invested in with zero risk.
I agree, but I doubt from their perspective it's a quick buck. I appreciate from the perspective of people who got a free service and it's now getting monetised it might feel quick, but surely not surprising at some point. And they got a quick buck up front from not having to pay for the service, which is nice :)
