Out of all things to hate Reddit for, giving data to AI isn’t something fediverse users can really criticize it for, though making money from it perhaps.
Remember: All data in federated platforms is available for free and likely already being compiled into datasets. Don’t be surprised if this post and its comments end up in GPT5 or 6 training data.
GUIs are way more complicated than you imagine, and require a completely different set of skills than developing the sort of program you mentioned.
If you want a nice, easy to use and well supported software, then pay for it and hold whoever you’re paying accountable for making it user-friendly. If whatever you are using is free open source software, then that’s literally !choosingbeggars
If you really think it’s something that can be built in an afternoon, feel free to commission a freelancer to make the GUI for you or see if the repository owner is accepting any sort of bounties/commissions. How expensive could an afternoon’s worth of work be?
