As someone who has a mortgage and children to feed ... Unity acquiring an ad company is encouraging. For years now Unity seemed to be lost and directionless; having them merge with an ad company shows that they're serious about focusing on creating a product that will help developers turn a profit.

But you won't hear many "indie" developers say as much, because making money is uncool.

That said, IronSource is sketchy as hell. I'm more concerned about _who_ they merged with then that it was an ad company.
