The main issue I have right now: the jurisdiction of this is in the US, and to be honest, I don’t trust the US that much when it comes to privacy laws regarding the (near) future.
I donate to Ladybird and Servo, and I hope they succeed. We need serious competition and a check on Mozilla (not to mention Chrome and Safari).
That said, I'm sad that neither Ladybird or Servo are licensed under strong copyleft licenses. We need user-oriented browsers now more than ever, and strong copyleft enables that. I worry that, even if these engines are successful, they will be co-opted by proprietary browsers and eventually superseded by them.
This happened before - both Chrome and Safari ultimately derive from KHTML, Konqueror's browser engine. If KHTML had been licnesed under the GPL instead of the LGPL, Chrome and Safari (and not just their engines) may have been free software today. Or, at the very least, it would have been much more difficult for Apple and Google to get started.
That said, I wish Ladybird the best. There donation = no influence policy is excellent, and I really, really hope they can stick to it in the long term.
Alright, read up on it a bit more. Sadly the language choices (C++ now, maybe Swift later) rubs me the wrong way for something that needs to be incredibly secure against attacks. I really really support additional browser engines, but likely not this one.
Thus I think Servo is a better choice for those looking to contribute. IMHO.
You can compare the WPT test results of many different browsers here. Its surprising to me that Servo lags behind Ladybird in successfully passed WPT tests.
Politics aside, I'd be curious to see how far something like this can go. Can't not think of Opera Software - even they were not successful while they were using their own proprietary tech.
