Could you do the same for me please?

Often when reading emotional comments, I wonder whether the author is upset about the product - or about himself.
You can separate yourself from a product you do not like (even if it means you wasted 50 bucks and some lifetime on it), but you can’t separate from yourself. 
So if the thread owner now feels better and can watch into the mirror again, maybe it was worth the posting here. I just dislike a basic tone of disrespect, putting oneself above all others, be it developers, other users or helpful minds here in the forum.

Yes, but Serif had to pay extra to develop for a different OS, test on a different OS, and support on a different OS. They need to be able to recoup those costs. Additionally, most users (I would guess) do not use both Windows and Mac, but only one, and Serif would like to keep the price low for those users who only want one OS.
Would you rather they raise their standard (US) price from (at a guess) $50 to $75 for everyone, to allow use on both OSes, when most of us want it on only one? I would rather have a lower price, because I know I have only Windows computers and am unlikely to get a Mac.
By the way, if you're a business user willing to do a volume purchase of Affinity licenses, you can get keys that will work on either Windows or Mac.
