Well, I think "no programming" is more clear to most non-programmers than "no coding". My mother, for example, who is in her mid 60s, would understand "no programming". She wouldn't understanding "no coding". My partner, who isn't half that age, and does use computers all the time, to her "no programming" is also substantially more meaningful than "no coding". In fact, pretty much everyone I know who uses "coding" in their vocabulary can code, at least a little. :)
As for the price -- I think a one-time payment attracts a lot more business than a recurring plan or a "until the next major version" approach where there is a new major version once a year, when your target audience consists of mainly hobbyists. I would almost certainly not have bought a license if it would have been almost subscription-like. I know that it's pretty common for development software, and I even agree that it's fine for company users (C2 has a business license, too), but for an end user and especially a hobbyist the model that Scirra went with is a far more appealing.
Or differently put, something like WebStorm and its annually update fee, or Sublime Text and its "until the next major version" way, those are expenses I can put on my tax declaration, because they are work-related tools for me, and my boss may even pay for them. It's different for C2, which is more or less solely for fun and hobby-stuff for me -- if it wasn't, I would have a business license and those do cost more than $79).
