Keep in mind that there is a tremendous difference between a motion to change and those that follow a certain lifestyle. Chassidus was rejected and thought of as deviant for a few generations. Now it is just another group of people. Rav Schwab and Reb Aaron would not say today what they said then.
If you were around in the days of wrap around Levush and you change to put on a Rekkel, you would be considered an outcast. Now, that is the norm (for Chareidim). Those that initiate changes are viewed with alarm, but an established group of Shomrei Torah uMitzmos are not bashed.
