I think they care, it's just that the whole community or certainly the majority of it needs to be behind whatever is done here and there is no real urgency to do anything immediately. DigiByte may have already accepted there is no such thing as ASIC resistant POW but a fundamental of DigiBytes overall security by design, requires that not more than one of the five algorithms should be mined by the same hardware. So, I reckon they have to be thinking about something to do here, still.
If that's the case, they should remove the whole 5-algos, decentralization, etc.. Jared said himself a lot of times that DGB was created because BTC mining became centralized. DGB mining centralized now, what's the point of DGB?
Don't pretend you know what devs are thinking and look at what they're doing. Yeah, they aren't doing anything about it.
