From business point of view they can make any decision they want to protect their business but in the mean time it's important to resolve any scam accusation too. It does not help just leaving like that. They are here from long time and should be know the reactions from the community.
Still good luck to them.
If they leave without solving the problem, the reputation their project has gained will be lost.
Only if the claims have real merit otherwise they will be fine. We can not ignore some users make noise because they actually think the community will take their side (accusers).
