Because there's no preselected default subscriptions like with Reddit. If it defaulted to subscribed when you make an account, then the first thing you would see is nothing. By defaulting to all, it allows you new users to see all that's available, and once you find a decent amount of interesting communities and subscribe to them, then it makes sense for you to manually change your default to subscribed at your discretion.

The first thing I did after creating an account here was to go to Settings and find the setting to change that. And I mean at least that option exists and is easy to find. My guess is that the feature of suggesting "subs" after creating an account does not exist yet and just showing an empty feed is not that great.

I think the main reason for that design decision was due to the small user base in the past.

You can do this in Lemmy, default the Home Screen to Subscribed. It’s an option for each user, but the instance admin can choose a default. I’m not sure about Kbin.

So you’re angry that you have to click your screen 2x and waste 9 seconds…. Instead you’d prefer every single new user to see no content at all?

Seems like an odd take.
