This is just a copy of freeware ImageOptim. Check the screenshots. The interface is identical. Developer is the same one in China making all the clone video downloader-converters (Total is one of the brands). Pricing at €33 for freeware is criminal. Someone is making a lot of money selling free software against the original license. I'd say delist this software except having reviews like this available might save some people paying for what is a real open source developer's work. Instead we should donate to ImageOptim (I have no relation to that software and do not know who the developer is - yet).
