If you think regularly interacting with shit content somehow helps you stay out of an echo chamber then go ahead and make a second account on those garbage instances full of hateful people.
So Beehaw has defederated from your home instance, are you implying that Beehaw is the "garbage instances full of hateful people"? Or are you saying that sh.itjust.works is and you tip your fedora to them for recognising it?
Defederation is a powerful tool which will no doubt be abused, especially with lemmy in it's infancy. I just hope that it isn't abused to the point of completely fracturing the lemmyverse, further confusing new users until they just give up and make an account on the "meaverse" (or whatever facebook endup calling it)
