The hype is unfounded. Yet another browser engine designed using the same tools with the same methods isn't going to yield an organization resistant to the monetary and social problems that Mozilla has faced.
It's not about the tech. It's about the org making the tech. Dev time is expensive, and there isn't a way to pay for it. Eventually people get tired of working for free and begin to treat life realistically - f#@$ you, pay me. That is the correct and expected outcome.
Ladybird as a browser has nothing special going for it other than hype. It's a walking vulnerability that has to play catch-up to be a contender as a web browser.
Chromium was/is "the" open browser, and it only happened because google and friends footed the bill.
Where ladybird and servo could shine is as an embeddable renderer that doesn't have to have all the other features of a fully kitted browser.
