The main reason they fud is because of how easily people in this market fall for it, and as long as that doesn't change, we will never see fud decline. The sooner everyone just ignores all the nonsense coming from a bunch of losers, the less incentive they will have to continue their pathetic practices. Main point of importance is that people start to understand Bitcoin and how this market actually works -- fud manages to affect people because they are ignorant. Take the ignorance of people away, and this fud nonsense will be something of the past. But then again, it's practically impossible to get rid of fud entirely due to the high influx of get rich quick newbies entering this market, but we can at least have it be reduced significantly.
In terms of adoption by the masses FUD is not a real concern as they do not know "enough" about bitcoin for the FUD to affect them. They are at an earlier stage eg I was in hospital over the weekend and said to the nurse i was a bitcoin fan.
She
1. has heard of it ie did not reply "What is bitcoin?" so its slowly getting down to everybody
2 had a basic concern about it not being a "real coin" ie it was just alot of numbers and she could not touch it like cash
I have others say things like it is too expensive as they think they need to buy a "whole "coin.
So we should ignore the FUDsters and spend our energy on possible adopters.
My answers to that not being real is to point out their bank accts and electronic wage payment to it each week are not really real either but they accept that as normal. To the issue of being too expensive I say that the word bitcoin should be seen for some meanings as word like "sterling" ie it describes a currency - you cannot buy 1 sterling but you can buy 1 pound. it's not an ideal comparison but it helps
