It absolutely is!
If Nazis can only exist on all-Nazi platforms, then it's vastly harder for them to make new recruits or to disguise their true intentions. ("I'm just asking questions! Also I have to ask those questions here on Stormfront, for reasons.")
Plus it's harder for them to fundraise--Pepsi or whatever might still find it acceptable to buy ad space on "free speech" platforms but they're not going to advertise on Stormfront. And the wealthy "mainstream" Republicans who slip Nazis cash under the table--they want to pay for mainstream exposure, they're not running a charity to help Nazis just talk among themselves.
So while it's maybe true that Nazis say worse things after they retreat to Nazi-specific platforms, they don't get to say them anywhere near as effectively or lucratively as they do on "tolerant" general-interest platforms.
