This may be one of those questions that might expose my half-baked knowledge in this field, so I thank the experts patiently explaining this to me in advance.
- What is the fuss about web browser engines?
As I can see, there have been many web browser engines in the past; most defunct / unmaintained and the three: blink, gecko and webkit being the only ones actively developed and maintained today (I am aware of Goanna, but some articles online say it isn’t being developed anymore – I could be wrong). What is stopping someone; say the FSF or some other group championing libre software from coming up with their own web engine completely different from the incumbent engines? I understand that not all web features will work with every engine, but surely we need more diversity than just the existing three to spur more development, right? Many software including the Linux kernel had humble beginnings and if enough people find it to be a suitable alternative, they might slowly jump ship to this new hypothetical web engine that was built using GPL3 from scratch.
- What is stopping web developers from simply shunning Google’s Manifest V3?
I haven’t seen or heard of one single good thing about Manifest V3 from any web developer (at least the six that I know personally), and have only read articles on why it is either unnecessary, or that the proposed advantages can easily be done is a less disruptive manner. While I appreciate that the internet today runs a lot on Google’s infrastructure and services, surely if Web Devs tell them to go pound sand, or intentionally break the site when using Google Chrome, and put a message saying, “Go to Firefox / Safari for a better experience”, that will make Google backtrack.
Once again, I apologise for these basic / daft questions. I appreciate any insight that you may have for me.
Building a browser engine is hard, especially when the target is moving at a rapid pace, and that target is controlled by Google. Like it or not, the web as it is today, is pretty much driven by Google (and to a lesser extent by Apple and Microsoft) these days. They can throw infinite resources into developing the browser engine and the browser itself. The closest competitor we have today is likely Servo, and they scrape by on pennies.
Developing something from scratch, with even less funding and expertise than Servo is a non-starter. It's not going to happen. Sure, sure, there's LadyBird and some other independent efforts, but I very highly doubt they'll ever catch up to the three major engines.
To develop and maintain a browser, you need people, and they need to be paid. Paying open source developers is... quite a big problem in and of itself, even for things considerably easier and smaller in scale than a web browser.
They would not, because for every developer who would do this, there's 100 who would not, because their livelihood depends on people with Google browsers being able to use their stuff. Google is in a position of power here: they are the #1 search engine, they are the #1 browser, they're pretty well positioned on the mobile phone market too. The vast majority of businesses (companies or individuals, doesn't matter) simply can't afford to go against Google.
If the vast majority would, then yeah, Google would backtrack. But that would require a coordinated effort, from the vast majority of the internet. Likely multiple months of protest. That's not going to happen, people can't afford it.
