It depends on what you mean by “Mozilla’s fate”. In general, we are setting a much narrower goal than Mozilla and hope that focusing on only browsers will allow us to keep things simple and more sustainable financially. :)

I've heard Andreas Kling say that they will not accept donations that have strings attached. This means they can never sell search engine placement to Google for instance. This is what ties Mozilla to Google.

Don't throw money away into non-browser related projects while constantly pissing off your loyal userbase.

Its easy to avoid the fate of Mozilla, don't get involved and distracted by lots of side projects.

Ask for money from the start?

Mozilla's fate? You mean building a browser that works?

Indeed, I doubt very much that Ladybird will get there.
