Did the Maskilim win after all?

Schneur Zalman of NY commenting to the Modern orthodoxy beNusach Chabad post:

The Rebbe Rayatz said over and over America iz nit Andersh. If it was different in secular studies, I would love to know how its not different. My point is that all Lubavitcher in the US speak lashon hamedina. No shliach could function speaking only Yiddish. The shluchim dress modern, give sermons in English, appear on TV and in the media. Please tell me what exactly did the maskillim in Russia want? They wanted Rabbis who spoke Lashn Hamedina, dressed modern, able to communicate with secular Jews and Christians, gave a speech once in a while, etc. Yet secular knowledge does not seem to have hurt Lubavitch in the US?
