Why closed beta? Wouldn't it have to be open source if they base it on Chromium?
Why don't they just make repository to get contributions from all around the world?
It does. It is based on WebKit, which is based on KHTML, which was under LGPL.
But if they haven't modified the LGPL code (which is likely), they probably don't need to distribute their source code.
You can still do closed betas with free software though, as long as you allow the beta users to get the source code (but they can, in turn, distribute the code to everyone).
They only have to distribute the source code for their modified Webkit, and IIRC have some way for end users to link in their own Webkit. That does not have the same vitality of a strong copyleft license like GPL. I guess this may still be classified as copyleft, but by no means does it require them to redistribute the source code of their browser.
Note that Edge is not open source, even though it is based on Chromium and contains Webkit-derived code.
Not an expert in the field, but the consensus I keep seeing is that:
1) Gecko is harder to embed and fork. Google built chrome to be "embeddable" from the start, while Mozilla slowly made it lower priority, possibly due to the lower budget.
2) Gecko is licensed under MPL, while Chromium-Blink is available in BSD. Even if companies are going to release the source code, its easier not to be under obligation to do it properly in a timely manner.
3) A lot of websites only support Chromium-based browsers, or are at least only tested on them. While we all like an underdog success story, it makes more sense to use the better supported option.
Someone more experienced can provide better insight though.
Browsers are growing huge. This may be the last time someone can enter the game. At some point, the sheer size and complexity will make the effort futile.
I think that if you'll focus on just the HTML5 and new stuff without any consideration for legacy things it's still a big undertaking but not impossible. There are projects focused on new browser engines, for example - Servo.
I am the complete opposite. Google is filtering results so aggressively (suppressing info along political lines, prioritizing big corp media, more and more ads) that its essentially unused anymore. Besides, a quick !g to your search and you can query google is your first attempts fall flat.
I use Brave search. I just tried "Duckduckgo browser" in both Brave search and google, and the 1st few top results were the same (except google had a load of ads scattered everywhere).
Obviously YMMV, but I rarely need to use Google these days.
Beyond general web searches, I just thought I'd expand on how I don't use Google.
For code documentation, I install Zeal and perform local searches.
For opensource information (medical, geopolitical, people, etc) I'll just search straight into Wikipedia.
For technical stuff, I'll search straight into Stack Overflow.
Honestly once you know where to search, you can pretty much skip Google search for 80% of the time. If Google / Duckduck Go / Brave search stopped working tomorrow, I wouldn't feel like I couldn't use the internet in an efficient manner.
