Except that mechanics are paid for their work and modders/resource pack artists aren't. Content creators don't owe you "maintenance" nor a reason why they stopped working on their content if/when they do. You're not paying for anything, so expecting modders or resource pack artists to forever support and update their content for free just because you want it is ridiculous. Be thankful that you got their content in the first place, because they could've not even released it at all or placed it behind a paywall. "Can they at least update [insert content] to [insert version]?" No, strangers on the Internet are not entitled to that. This attitude is what discourages many content creators from working on their content in the first place.
Also, you don't need a "5 year course on programming" to update resource packs. As long as you can do basic file navigation and text editing, you can update most packs yourself (the more recent, the better). It may take time, but it's usually not "hard" per pe, just tedious.
Capricocious's statement still holds true: if someone isn't updating their content that you want, ask them nicely if you could do it, and then help them out and do it yourself.
