There are only a limited number of browser engines out currently and lady bird adds another, hence diversity enhancement. Omarchy is +1 more distro out of thousands, hence while making the "market" a little bit more diverse it's not a huge double-digit percentage increase in viable browser engines. Pretty straight forward.
I think the parent comment means that Ladybird is fighting to be an additional browser engine in the current ecosystem of “Chromium and a couple of tiny, unimportant competitors.”
However, on the subject of the other meaning of “diversity,” and whether or not it is in the business models of either of these projects, I think we have pretty conclusive evidence that actually it is NOT a core value to either of them:
As someone directly affected by this sort of thing, I really want nothing to do with either project.
I also can’t help but notice that this “tech-right smell” is about the only thing that these two projects seem to have in common with one another, making me question Cloudflare’s intentions with this.
What does this even mean? And if it's an important part of a business model, how do you know that Omarchy isn't?
