There is a nuance missed in the discussion so far - Starlink is creating a new product level, differentiating service between continental and intercontinental aviation connectivity. Previously these were a single category.
If you are operating in North America for example, your service is going from $10k to $12.5k. Still a 25% increase, which is not fun, but I think a lot of the customers affected by this will fit into this category. You only need the $20k plan if your aircraft travels between their roughly-continental regions.
Nicholas Air, quoted in the article, appears to have no need for the $20k plan and should not use it.
