I really don't mean to sound harsh, which is why I refrained from posting on this topic before, but I really want to stimulate a discussion:
If you aren't making at least $1000 per game, and you take more than a month to make a game, you should review your options. Yes, it's a hobby, but we'd also like to make money off of this, and it appears scirra is trying to cater to the professional developers as well.
Granted, we don't have things like FGL for HTML5, but that might change in the future. Monetization options like Facebook credits aren't that far off, and I believe the only reason someone hasn't made a plugin for that yet is because too few people requested it.
Really consider what you're doing for a moment. If you are spending time creating games, you're already spending money, because you're wasting time that could be going to a better paying job. If, however, you create games purely as a hobby, then you shouldn't complain too much about spending to create and/or publish them - besides, the mobile platform isn't that big on hobbyist games anyways.
If you want to go professional, and really want to make money, $150/game/year to publish is a bargain, especially considering the costs associated with creating (programming+sprites+music+SFX) and hosting the game.
