So let me see if I've got this straight. I can go to the Windows Store to get Paint.NET, in which case I will have to pay USD$8.99 for it. Or I can go to getpaint.net to get Paint.NET for free, in which case I will expose myself to a barrage of misleading ads designed to get me to download malware (see https://jasonlefkowitz.net/2013/03/google-and-paint-net-need... -- I wrote that four years ago, but the ads are as bad today as they were then).
"Now you can pay us money to skip past the part where we try our hardest to screw up your computer!" is a real innovation in software marketing.
