Reddit changed their policy yesterday with this post.

We also want to reiterate that we respect your decisions to do what’s best for your community, and will do what we can to ensure you're safe while doing so. However, we do expect that these decisions have been made through consensus, and not via unilateral action. We ask that you strive to ensure that your moderator team is aligned on community decision-making – regardless of what decisions are being made. If you believe that your community or another community is being subject to decisions made by a sole moderator without buy-in from the broader mod team, you can let us know via the Moderator Code of Conduct form above.

It's old fashioned union busting tactics. Try to foment internal discord and break the strike. Until yesterday, the head mod was king and could do whatever they wanted. Administrators have upheld this standard for literally 15 years. Interesting how radically it changed yesterday.
