People satisfied with a product are generally busy using it instead of writing about how happy they are with it. The others, not so much. People are more likely to speak out/write a bad review when disappointed in a product rather than when they are happy or receive a product as expected.
In general though, user criticism can be a fair indicator of what at least some people have found lacking, and a lot of times its not just a matter of the majority or minority of users that makes a problem worth addressing. Just because most people have accepted something the way it is doesn't mean it can't be improved. Whether or not it is worth the time and resources to do so is up to the developer of course, as they always have to balance the priorities of anything they work on at any given time.
Complaining about the price or pricing model is literally pointless though. There are uncountable examples of irrational pricing injustices in this world (Construct is not one of them), and no matter how much you complain about it, the price is STILL always going to be set by the one who offers the product. Complaining here on the Construct forum about the price simply reinforces the fact that they have created something that is desirable to that person, otherwise the complainer would simply have left for a competing product, of which there are plenty.
Anyways, thanks Scirra (Team Construct?) for your hard work. As always I'm blown away by your dedication to continually improve evolve Construct rather than just release a product and let it be. More so than that I admire and am envious of your ability to interact with the community so regularly and in such a close manner without going completely insane.
