  • Generally speaking the use case is writing tests. If your tests just call all the dependencies and new directly then it’s harder to write tests for your specific component while avoiding setting up a whole bunch of stuff (to make all those other classes work). By requiring all the dependencies to be provided to the class, you can swap them out at test time for something else that’s easier to work with.

    That said, IMO it’s a symptom of problems in language design. Using DI is only necessary because languages like C# don’t make it easy to mock out new or classes used directly, so we resort to wrapping everything in interfaces and factories to avoid those features and replace them with ones that are easier to mock. If the language was designed such that those features were easy to replace during testing then DI probably wouldn’t be a thing.


  • My point is that the data on here is purposely shared with every other federated instance, there’s no semblance of privacy and your data is shared with hundreds or likely thousands of admins by the time it’s done (more and more as the network grows). There’s no reason to trust that every admin will keep that information private, some people are already talking about putting up services to expose all the hidden information (in the name of “transparency”). It’s simply trivial for Meta or anybody else to get copies of the data because there’s no real protection from it unless you’re making your instance an island (and that’s an island from everybody, not just one specifically known to be Meta).
