As you said in your first post, substack provides “high walled gardens.” In all the time I have been on Substack, my walls have been high enough neither I nor the neighbors ever filed noise complaints. Until you wrote that, I had never heard of any of those morons, and I found out none of my subscribers had either. And your “alternatives” are about as good an alternative as Threads is to Xitter (pronounced “shitter”). An nobody still hanging out on Xitter for the contacts need say a damn thing about anyone anywhere doing anything.
