Logician: Interesting speculation about how the ban came about and why it was instituted, but there’s no need to speculate: I wrote several posts above that have the factual background — and it has nothing to do with what you surmise.
I suggest you read the hebrew language discussion boards and you will find out more about the political connection between the “Eitz” activists and the Lakewood Rabbonim who also advocated for this ban, getting other Rabbonim to then sign.
I suggest you compare the false claims made in the two kuntreissim that were shown around in Lakewood with the same claims made by the Eitz people — and which the Eretz Yisroel Battei Din said were not true. (For instance that the people producing this work were not ehrliche yidden. The Battei Din declared this a lie, so the Eitz people turned to Lakewood to advance the libel that they could not advance in EY, where the editors are well-known and where the battei din investigated them thoroughly.)
