Avira, you love finding the worst in everyone (Briskers excepted). It is an easy-to-verify fact that there are shuls full of people who learned by Chabad shluchim, and even in other places there are people who learned by them. If Lakewood kollelim have a similar effect, then great. Now, if some of them are not doing things right, you are free to direct them to better understanding and mekarev them into Brisk.
Again, we are confronted with 4 mln drowning Jews and we are barely saving 1% of them.
