Yes, but only after fracturing the ecosystem even further unfortunately.
Anaconda is a good example of this.
Yes, but how far apart will the fracture be? For instance, Mac and Windows are further apart than Ubuntu and Fedora, despite both being fractures in the OS 'ecosystem' - it's far easier to be cross-platform between Ubuntu/Fedora than between Mac/Windows.
Most forks eventually die.
I'm not sure immortality is a good standard to hold forks to. the original project won't last forever either.
There is yet one to exist that dies before its forks.
Hudson died well before its fork (Jenkins)
Bad example, because the fork is from Hudson authors leaving Oracle, not from a bunch of people angry at the authors.
Ah yes, of course, no true fork has outlived its upstream project, how silly of me.
Most !== All
Then why did you say, "There is yet one to exist that dies before its forks."
