I suspect youre right.
I think they may have assessed their business model and seen how unviable supporting a shrinking customer base of small users that complain (and rightly so) is becoming.
If they dont address this problem, I think it is a sign that they are molevolent in their actions.
It speaks volumes about their intensions, as does their lack of regard to existing raised issues remaining unreslved year on year.
It may be wise to at least research alternatives so that we have something ready to pick up the pieces when the fallout occurs. Assuming most have not already moved on.
