That either reads “we don’t have the resources to support our second largest OS platform” or there are too little users still using the native desktop client.
Mind you, this is a company that went out of their way to port a Linux client in 2011.
Firefox and Gecko are going to die because the vast majority of people do not care about layout engine monopolies. Corporations rely on the vast majority of people. What will probably happen is as Mozilla goes bankrupt, they will spin off Firefox's development structure to a more community driven approach. Then, Firefox and all of its derivatives will continue to live in Linux/Unix Open Source world. Let's face it, political software issues are developer centric. From there, Firefox will end up like Galeon and Gnome Web, slowly losing relevance, lacking modern browser features, and lose development support over the years because a layout engine is very complex and MUST have a corporate backing. Microsoft proved this themselves with their decision.
All of these articles love to fear their listeners by warning them of another IE monopoly situation. None of them seem to mention why monopolistic browsers are an issue, or even how history will repeat in this crazy modern internet world. The only point anyone's made is that security vulnerabilities will span across all browsers. With that logic we might as well write all programs in different languages, and use 20 different operating systems. Obviously that isn't efficient and neither is wasting development money on yet another layout engine. But hey, it's fun to worry about petty issues, so I'll keep reading these blogs.
The initial idea of Facebook is great. I can't exactly knock it when this site is heavily influenced. But the problem with having specific boards that satisfy every little interest is that an echo chamber effect often occurs. My karma on that site is so low, not because of trolling, but speaking my own opposing views. I'll never be able to post on a FreeBSD subreddit, claiming a specific case where I find Linux better suited. Or when I read the OpenBSD mailing list and post that Theo De Raadt needs to get a grip, when he rejects Rust because no core utilities have been implemented. Making points that radical are just asking for trouble.
It's a great way to collaborate with people within the same niche, but it's a clique. They only want to hear themselves talk. Believe it or not, despite 4chan's well known toxicity, boards like /g/, /adv/, and /mu/ are perfect examples of true anomity. Where specific interests are shared within threads of each board. They may come off harsh to the light hearted, but they're not afraid of opinions.
