I rarely have the need for image manipulation, and when I do my needs are simple and well met by open source software. Surely a calendar overlay on a photo does not require top shelf software. And there are plenty of frugal, if not starving, turbine pilots out there. Not to mention more than a few who might be philosophically opposed to using "big iron" software (e.g. Microsoft, Adobe, et al).
At any rate, here I am trying to do a favor by providing a perfectly serviceable path for those who don't want to buy a license, or <shudder> a subscription (a most insidious way of emptying a wallet) and thereby open up a larger pool of potential volunteers, and I get slagged for it
