They're developing a new web engine, so an alternative to Blink/Chromium, Gecko, and WebKit.

The problem with Blink is that it's controlled by Google.

The problem with Gecko is that it's not portable at all - it can basically only be used in Firefox and Firefox forks. It's completely Mozilla and cannot be meaningfully detached.

WebKit is controlled by Apple, and GNOME Web is basically the only browser other than Safari using it.

Servo is modern and has some technical advantages I don't fully understand. It's made to integrate well in other projects, making it easy to integrate the web into all sorts of projects. Development was started by Mozilla, abandoned, and then taken over by the Linux foundation.

I don't trust Mozilla these days, and I never trust Google or Apple (though WebKit is cool). So I'm placing my bets on the Linux foundation.

(Web independence is of course many things, but I was thinking in terms of web browsers. Obviously a lot of open source projects contribute to the independent web in all kinds of ways.)
