I know how to fix it - installing Visual C++ redistributable solves the problem
I've not heard of this before, and it's a bug if it's the case. Have you filed a bug report? Ideally the NW.js exporter can work at best performance without having to install anything extra (other than the DirectX web setup thing, which is a pain, but we had to have that for Construct Classic as well, which used... a native exporter).
I don't think we'd make more money with a native exporter: it is an enormously expensive project, requiring more staff, more development and testing time, and other far-reaching implications (like third party plugins essentially become unportable unless the developer feels like doing 5x as much work for free). We'd probably have to put up the price of C2, or charge per-exporter like some other companies do, running up a high cost for the customer if they want all the export options. Given that it has all export options built in, C2 is one of the cheapest tools on the market.
Independence from third parties never goes away unless we write our own operating system and device drivers. We could for example choose XNA, Haxe, Flash, or something else, and equally be hosed by problems in those frameworks.
It's true we don't have control over the performance of browsers. It already works great on most browsers though. The performance of modern browsers is improving at an impressive rate. I haven't heard any complaints about the performance on desktop for as long as I can remember now, and I think that's enough to prove HTML5 is not fundamentally slow. The only reason mobile is sometimes slow is due to a Crosswalk bug that hung around for a while (and should be fixed in due course so it performs identically to Chrome - it uses the same codebase), and possibly the fact Cordova still doesn't use JIT on iOS by default (which should be fixed in iOS 9, and despite this I have very rarely heard of performance issues on iOS, so it seems to be OK already!) As I've said before... anything which has a fix on the horizon isn't much of a reason to give up on the technology entirely.
