How did the Dollfuss Revolution of 1934 affect the musical organizations Anton Webern worked with?

The "Dollfuss Revolution" of February 1934, which saw the authoritarian regime of Engelbert Dollfuss suppress the Social Democratic Party, led to the dissolution of two musical organizations with which Anton Webern was closely associated: the Singverein and the Workers’ Symphony Concerts.12

Both of these groups were sponsored by the Social Democratic Party. Following the political crackdown, these organizations were disbanded, effectively ending Webern's role as a conductor for these ensembles.1
