At some point, I do think that the DHF should be moving on from funding front-ends to newer things, but I don't know if they can survive as they are right now.
That! I would agree with you on "defunding" frontend, but to do it gradually, and leave some time to transform those front ends into self-sustainable projects... But, without defunding, that will never happen... And it doesn't look good nor for them, nor for Hive holders in general...
