Tangential but I've recently discovered that an app I've written and published on F-Droid has been forked and put on Google Play with ads on by some Chinese forefront along side a lot of other open source apps without any mention of their GPL of course (and Google making it ridiculously difficult to take down thoses for normal folks, having to use a legally binding DMCA form).

Thoses marketplaces are filled with cheap softwares made to make a quick buck by any means without a thought for the whole user experience, with no way to flags grifters for a better community driven experience.

The economy must thrive I guess.
