Just wait and the problem will resolve itself when proper mod tools are released and beehaw refederates with open instances. In the meantime you can still read and interact with beehaw posts, but only with a separate copy of the post which is only seen by other lemm.ee users. The post you linked to creates a false sense of urgency where unless you can interact fully (i.e. as if beehaw is federated with lemm.ee), then there’s no situation where you should read or interact with those posts at all, or that you can’t interact at all. That’s not really true, as some comments on the post pointed out
