As some subreddits continue blackouts to protest Reddit’s plans to charge high prices for its API, Reddit has informed the moderators of those subreddits that it has plans to replace resistant moderation teams to keep spaces “open and accessible to users.”
Edit, there seems to be conflicting reporting on this issue:
While the company does “respect the community’s right to protest” and pledges that it won’t force communities to reopen, Reddit also suggests there’s no need for that.

It’s not forcing a sub to open.
It’s removing mods that are squatting on a sub or vandalising a sub, as per described in the mod guidelines.
Whether the new mods that Reddit instates open the sub or not is up to the new mods.
They can say the first and do the second. The mods they instate will open the sub.
