This is an economic problem, not a technical one. From the article: > “Linux is a small market already and if you subdivide it by blessed kernel versions then it’s even smaller.” It may not be worth Epic’s while to put in the work on security for what will be a comparatively tiny audience, at least at first. For many products, there's not currently an economic incentive to support Linux because the development cost, support cost, and opportunity cost outweigh the potential revenue. I'm sympathetic to this because it's something I face with my own product. In many cases, the Linux market currently isn't large enough to justify the cost, but I hope that changes in the future.
