I'm talking software products here. Clearly you don't know much about IT and software development.
Buying something like XF for a hobby board would probably still be fine. No real issues there, you can probably continue to run it for many years even if development totally ceased forever.
Commercial enterprises simply won't wear that, however. And for something like XF to have a viable future, those big enterprises that currently run vB and IPB have GOT to start switching over. That was starting to happen and it was fantastic. And now.....no.
Again, people can pretend none of this matters. The big problem is, it DOES matter. And worse than that, the longer it goes on, the harder it will be to recover the previous good reputation.
