A more equivalent comparison is Nazi ideology in Germany/Austria to Klanist ideology in the United States. The list of US politicians with Klan affiliation is long.

FWIW, I don't have a particularly strong opinion on whether laws banning Nazi speech have a large impact on the number of people supporting that ideology. I don't think they increase the number of Nazis, and it makes sense to keep them around given the historical context of countries like Austria and Germany even if they don't have an impact on that number.
I do think you're quite far off the mark if you think less than 0.001% of the U.S. population identifies with Nazi ideology, while it's something like 1% for Austria and Germany.
I think that for the same percentage to identify with Nazi ideology it would require millions of people to be so comfortable with it that they would openly give Nazi affiliated parties their support.
I don't think millions of people support Neo-Nazis in the US.
Also, The Southern Poverty Law Center estimates that there are 190 active KKK groups with between 5,000 and 8,000 Klan members in the U.S. That's a far cry from Austria and Germany.
That's the main reason I don't agree with the banning of daily stormer and google banning Gab.ai from the play store. They are only further enforcing these people's beliefs that the powers that be are against them.
No one is saying they can't discuss their beliefs, they just can't do it with the support of certain private companies. In the same way, if I owned a restaurant, I wouldn't allow them to host an informal "Daily Stormer Night" at my restaurant. I shouldn't be forced to having to have them use my restaurant as their unofficial homebase.
A lot of people are saying that.
Here's where it gets interesting. If you leased an apartment, could your landlord evict you for for hosting dinners in support of the KKK? That's more similar to what happened with the hosting and service provider denials.
And I've yet to find someone who has said they can't discuss their beliefs. They just don't get "our" support to do it.
It wouldn't surprise me if all of these services have some verbiage in their TOS or contract that allows them the right to stop service if the content being served is deemed to be inappropriate by them.
For example, according to the Southern Poverty Law Center (not a group with an incentive to deflate numbers), at its peak the National Alliance had 1,200 members. All together, there are a few thousand active Neo-Nazis in the United States.
In contrast, let's take 2 countries where advocating Nazi ideology is illegal: Austria and Germany.
In Austria, the Freedom Party, founded by a former SS officer, has 50,000 members, 13 seats in the Upper House (similar to the Senate in the US) and 38 seats in the lower house as well as 4 in the European Parliament.
In Germany, the NPD received over 600,000 votes in the most recent election and now has a seat in the European Parliament.
