What’s the alternative to Unity? They have a huge market share and mind share among game developers. Some might be driven away but others will stay and show lots of ads. If this does eventually drive someone else to create something that takes Unity’s place, Ironsource will have made a giant pile of money running Unity into the ground.
Tragic for everyone else, great for Ironsource and it’s investors.
Not making games. Unity has won big on the indie game community flourishing, of more people making games. If Unity stops being a valid choice, or starts being scary, some of the people making indie games might decide making games isn't worth it.
Sometimes we think of economy in terms of necessity. Some idea that people will make games, it's only a matter of how, but Unity didn't get big by cannibalizing some existing market of indie games. Unity was part of creating that market.
It depends on what you are targetting, but there has been a huge surge in interest in both the Unreal and Godot communities since the announcement was made.
Alternatives exist and while it takes time to adjust if you are deeply invested, it will occur.
Nothing causes people to abandon ship like a torpedo.
