How could you be so confident about such a thing?

Are you implying it's going to fail in its goal as a competing browser, or that the competition is somehow irrelevant in a world that's forced to be slave to Google/Apple?

I'm implying that Ladybird will never grow to the size where it will have any influence on the internet. So this donation is a token gesture to making things better and will be unlikely to change anything.

I dont think Ladybird will ever surpass Firefox and to have any impact it would need to be at least as popular as firefox.
