BM has been in active development for ages now with a huge team of developers, they have gone through tons of hacker attacks, and they have a pretty good ranking on ModDB. Then there's also the astounding achievement that their fan base can bring down GamerNode in 10 minutes...
They have some kind of recognition from VALVe, as they told them to remove the ": Source" subtitle (but they did not tell them to stop building the mod, which says they are fine with its existence).
I guess the BM people could pack it up at random some day, but at this point in time and this far into development it seems unlikely.
Working on a mod like this would look great for future job prospects for those guys, but only if it actually was finished. Not finishing would be a waste of a lot of work.
(Of course, after the public beta stuff, I imagine they'll get rather sick of it as with even the successful mods).
