The title doesn't match the content at all. The content is correct in that pricing apps is complicated and there are factors that people don't often consider. And that support costs should be a factor. But nowhere does it prove the should be paying more . Maybe the developers could charge more, but it doesn't even prove they should do that.

One of the major points raised is that pricing is largely elastic; i.e. raising or lowering your prices doesn't affect revenue. This may mean in some circumstances the correct price is the one that is so high that it leads to just one customer. If it is the case that the pricing for this product is highly / almost completely elastic then a high price makes perfect sense. Just look at Apple's pricing strategies. [Edit…
There's a lot that goes into pricing, and most of it is not obvious at all.
