Well from their site

Moderation

Since there are no global admins, the administrative control of a subplebbit rests solely with its creator. No one else can moderate content or accounts unless the subplebbit creator grants them permission.

So, it’s not that theirs no moderation. It’s just “subplebbit” creator/delegates controlled as there is no over arching site wide company able to moderate it on the whole.

It will mean, as a user, you’ll have to be liberal with removing subplebbits from your own feed though. I’m sure there will be some… not so pleasant subplebbits appearing.

Conservatives? The UK’s current government is not a conservative one.

Though I don’t think the political leaning of the party in power matters here, as this is what governments do in general. Find ways, and justifications, to expand the scope of their power, often by using “desiring safety for insert demographic here (usually children)” and managing to get it through. Often without thinking what future, potentially more tyrannical governments, might do with that power.

If you are on Linux locally, you could try using sshfs, to “mount” the remote system to your local one and use your local dev tools. Though I suspect that would be against the spirit of what company is hoping for.
