Rust has a healthy number of committers who are not employed by Mozilla. I will let pcwalton fill in details if necessary.

"Proprietary" as in "sole proprietor" is appropriate for a project with zero governance, launched by Google after some incubation closed-source, dominated by Googlers.

NaCl is not adopted because it's machine-dependent!

PNaCl is not ready. Show me Chrome Web Store games compiled with it and not NaCl, then we'll talk.

As I've written before on HN (see https://news.ycombinator.com/item?id=2998374, "I've paid my dues"), JS was created by me in a tearing hurry in 1995 for Netscape, the would-be market power that nevertheless avoided a monopoly conviction (unlike the other guys).

There is no "quasi-monopoly" here. Someone on HN schooled me on "monopoly" (http://news.ycombinator.com/item?id=2998590).

The issue with JS is not "monopoly" in the econ 101 sense. The issue is that JS is more than good enough, and getting better under competition and cooperation in the standards bodies. Therefore it is very hard to displace, and just as hard (if not moreso: a displacing language might be backward compatible) to supplement with a second language/VM in all browsers.

You should respond to this technical fact (by which I mean, the circumstance is well-founded in software costs).

According to the Apache project, a project is "considered to have a diverse community when it is not highly dependent on any single contributor (there are at least 3 legally independent committers and there is no single company or entity that is vital to the success of the project)." Rust might meet that standard in the future, but it is not there yet.

With regard to JavaScript versus NaCl / PNaCl / etc-- I've heard all the debates before, and they are kind of tedious. ECMAScript is a good language for some things, but making it the only option is goofy. I think Mozilla is shooting itself in the foot by not supporting PNaCl, which is the one thing that could potentially save their "boot to Gecko" initiative from disaster. I guess the Adobe Flash and ActiveX experience left emotional scars that haven't healed yet. Oh well. Their loss, Apple/Google/Other app stores' profit.

There's nothing to "support" yet with PNaCl. It's still at the "we have no idea how to make this work" stage, last I checked.

And if it _could_ be gotten to work, you still haven't addressed why Mozilla should be willing to get on the Pepper "upgrade to keep up with all this unspecified stuff we're changing" treadmill.

It's not just scars from Flash and ActiveX; it's a distinct reluctance to bet everything on a technology you have 0 control over, and which one of your direct competitors controls completely. Now why would Mozilla be hesitant to do that? You tell me.
