Right now a lot of us are trying to divest and diversify from having our entire lives on Google both because of the way Google spends its money and the long-standing privacy concerns seeming a bit more scary now.
What services have you switched to and what has your experience been? What do you like, what don’t you like, would you recommend them?
So, it depends on google
No it doesn’t. If Google stops supporting it, the community forks it and continues development. Has happened often in the past.
You can’t just fork a browser engine. You need a lot of resources to keep one alive. The only browser engine that I know of which was successfully forked was goanna. And that’s a gecko fork from when it wasn’t even multithreaded, and it still took years.
