One of the reasons various Roshei Yeshiva were against it because of the way it was portrayed in the press and may be perceived, ie the way people here thing YU gave a psak that its okay to do mishkav zachor. This whole forum is proof to the phenomenon of “broken telephone”, but hindsight is 20/20.
Also I know specifically from Rav Twersky’s speech, that with regards to those people suffering themselves, they should not discuss their taivas in a public forum, the way everybody else does not discuss their taivas in a public forum since it is inappropriate. And that when they seek help, which they should, it should be done privately.
If my memory serves me correctly, the idea of being more supportive (in a way that enables these unfortunate yidden to believe it is possible for them to gain control of their taivas and stay frum) is a positive one, but this was not the way to go about it.
I just googled it, “curiousjew” blog that sam2 said to look for also has a transcript of R Twersky’s response.
