I thought the same thing when I found out about that, but it kinda makes sense.
Facebook tries to show you the most "interesting" posts. If you are a member of many groups, there are probably too many posts in your groups to show all of them in your newsfeed. So Facebook just picks whatever they think is interesting.
Or the poster can pay to have everyone see the post.
Anyway, I prefer this monetisation strategy to creepy tracking.
Facebook might pivot towards other monetization strategies when their cross-platform web tracking ads don't work anymore.
For example, Facebook offers you to pay to "increase the reach" of your posts. This happens for example when you try to post a message to a Facebook group. If you want to make sure all members see the message, you have to pay.
This is a way that Facebook monetizes without tracking (targeting is based on people who opted in to join a group) and the users pay directly in the app (allowing Apple to get their 30% for the in-app payment).
With Apples changes, Facebook (and others) might focus more on strategies like that.
Right, but I don't really see why you would need separate accounts. In my experience a single account for multiple projects is actually very convenient (with rules to automatically sort incoming mail).
In my opinion, multiple accounts are really only necessary if you have employees or collaborators and want to make sure that not everyone can access your stuff.
But that's just my point of view, I understand that what works for me may not be suitable for your projects.
According to their website, Fastmail allows up to 100 custom domains on a single account, so it's not like you need to buy a second account if you just want to receive/send email on a domain.
As a Swift dev, the reason why it slows me down is that I often end up fighting the type system.
I start with a concept, design my data structures on the whiteboard in a way that makes sense, then I try to code it and because of some detail in the type system it doesn't work, and I end up spending huge amounts of times wondering how to translate my concept into code.
