But C2 won't have upgrades in, say, two years. And then it's dead. And when new technologies arise, and new incompatibilites appears, our software is dead.
I think in very, very, very long terms (around 30-40 years) because I'm super concerned about "digital death". So I only use or tend to use stuff that has a very long longevity. I believe HTML5 (and 6, 7, 8, 9) will be around forever.
But why should I pay for C3 when Unity already has a WebGL export? Also Godot. Also UE4, and many other engines.
True, besides if C3 brings WebAssembly, I'd pay a subscription fee.
Well, Unity WebGL export is very experimental, I wouldn't recommend you to use it for production because it will have low fps in iPad.
