chasidism

Question

You blamed the fact of unnecessary chumros on the chasidim.You said that we must follow the mesorah which is to follow the gedolim and not start making changes.Didn't the chasidim have tremendous poskim that felt chasidism was right? The satmar rebbe zt'l was a giant in torah.(Pretty chashuv to have r' aron kotler zt'l speak at your levayah.)So how could you say that they're not following their mesorah when they have their own gedolim who also spent their wholes lives dedicated to torah, that say they're right?
