No, it's a symptom of having more of a very specific type of customer who is more demanding and difficult to please than your other customers.
When you don't officially support Linux, the Linux users are not surprised. It's normal for them. They find other ways to use the product.
When you do announce Linux support, you open Pandora's box of complaints. They're extra angry that you claim Linux support but it doesn't work perfectly on their unique combination of laptop, distro, display protocol, and window manager.
You gained a small number of happy customers, but picked up a disproportionately large number of angry, vocal customers in the process.
I wasn't looking to anger you, just to provide a different lens in which to view the situation.
