I don't want to turn this into a finger-pointing exercise, but I downloaded a free version of one of the apps mentioned in this article, and to put it bluntly, it's not very good. (I wanted to buy the for-pay version, but decided not to after I tried using the free one.) The controls are awkward, the workflow is confusing, some of the settings make no sense to me, and it does localization wrong so there are parts I can't quite use. I'll give anyone a bit of a pass if they're actively working to improve it, of course, but it also hasn't been updated since last year.<p>In "Dune", the Duke says "Let us not rail about justice as long as we have arms and the freedom to use them". As an 'indie' Apple developer, Apple's policies frustrate me as much as anybody, but it's hard for me to find a lot of sympathy for someone who has a free trial with a 3-star rating, that hasn't been updated in the better part of a year.<p>It's convenient to think that Instagram is beating us because of name recognition or advertising or iTunes search favoritism or whatever, but maybe it's because they've got a 5-star rating (the <i>average</i> of 700,000 reviews!) and their last update was only 2 weeks ago.
