Lately, I've changed my perspective regarding addon developers (aircraft, scenery, etc.). Today, unlike before, I realize it's not possible to sustain oneself solely on the financial returns generated by this work, due to various factors, one of them being the fact that flight simulation is a niche. There aren't many people engaged in this activity, and even fewer are willing to spend money on an addon, as many believe that upon acquiring the simulator, they should already have access to everything.
In summary, I might be wrong, but I see development more as a paid hobby than a job that provides a constant income. That's why I don't think it's fair to question or pressure developers with inquiries like "When will it be ready?" or "It's taking too long...", especially when updates are free.
