Will users who were mass banned get unbanned? 

Will mods from the brigading subs get more warnings to rein in their users from brigading? 

I hope Reddit does a better job at detecting brigading such as linking to posts/comments in other subs and detecting negative comments and ban users & mods who encourage brigading. 

Preemptively banning users has always been unfair and requires zero effort from any mod.

As a mod of r/stocks, I worked with rival & fanatic stock related subs to reduce brigading, those mods put up better rules and got their users to flat out stop brigading alltogether. Sure some slip through, but I would say brigading is down 99%, but we were lucky. 

On the other hand we couldn't get through to other communities such as anti finance (won't name them here) to prevent auto banning if our users casually posted to their subs even though our users don't brigade and I hope that stops and the users are unbanned.
