While it may have taken this soft fork to trigger the news and install the potential FUD that it may, unfortunately, bring. It still was possible the whole time and thus never really changed in terms of dpos security and quality (although perception is of course important).
Also, the demonstrated negative effect that one entity of aligned witnesses can have also reinforces the argument for why it is so dangerous for one giant stakeholder to be able to vote in all the witnesses needed to have super majority...
My preference would be that following this, we reduce the total witness vote to 10. While it will still be theoretically possible for someone to spend a hundred million dollars (assuming they would make price go up) in order to get the stake needed to vote in 20 witnesses, it would take a lot more stake than it does right now.
That said, I can understand that in the face of such a vulnerability, witnesses find it responsible to "pause" the ability for that to happen until a workable solution or sufficient clarification/guarantee is in place.
