Actually, the onus on the developers is to know python, or JavaScript, or a language such as those. You seem to be confusing marketing, or service, departments with engineering. Devs are not in public facing role. They code what they're asked to code, for the most part. Don't understand why people keeping blaming devs for not responding to forum posts. Unless it's a bug report, why would they bother?! If you have a problem with a website, do you contact the customer service people, or do you call headquarters and demand to speak to someone who worked on the code? That said, communication is generally abysmal, the app is screwed up badly.
You are absolutely right. They have forgotten the principles of development. You should not and must not test your own code. That should be up to a dedicated testing department. I know, I was a Lead software test engineer for a multi-national video surveillance software engineering company. But he accused a person of racism based on a comment. Stay on topic..... I would bet money that CG doesn't have a dedicated software test department. Otherwise, there wouldn't be as many defects and bugs. I didn't confuse anything. CG_Meathead is a designated rep for player interaction. So that is where I send my e-mail.
