Greetings @Veykek , thanks for raising this question about thunderstorms.
As @PoptartJuniper commented, this is an intended design decision that the developers have made, or it is in-fact working as intended. While it may seem silly to you, many adults are afraid of thunderstorms (I myself being one of them 😳). Since this is intentional, the team won't be making changes to it at this time.
In regards to staff visiting the boards, we are definitely around and responding. We have a great team of around 30 staff across the forums checking in, replying, notating feedback and issues, and producing reports that go to the studios on matters within the boards. While we're definitely reading the content that gets posted, due to the sheer volume that gets posted we typically limit replies to game critical issues, heavily engaged threads, and threads that we can provide a definite solution for at the time. We are also supported by a great group of highly knowledgeable volunteers that help answer some of the more common questions and concerns, you may have seen them around: the Heroes and Champions, these users have extensive knowledge of the game and have extended access to EA staff to gain clarity on pressing issues.
While you're more than welcome to provide this feedback on the Sims Games forum, the answer will remain the same that it is working as designed.
