Why not provide either hex editor or wasm as options. Let the user choose. The former is not trendy, it's time-tested and has no ties to a commercial entity or the online advertising "business". Whereas the later has only been around since 2015 and was introduced by a company that subsists off an agreement with a deviant online advertising company. Not to mention it targets "the web", which is only one use for computer programming, and one that is overwhelmingly under the control of a handful of large corporations.
