Ask HN: Is it alright to fork an apk and sell it without making much changes?

Given Psiphon's popularity, and the usage of VPNs in places where there are restrictions on the usage of the wireless network, this guy ripped off Psiphon's APK, changed the logos and other assets and uploaded the same on a Play Store account, without any credits given to Psiphon.

Whenever I see an update on Psiphon, like a feature to save data usage, I see the same reflecting in the copied app's changelog which is, I guess, a bit weird.

Shouldn't something be done to actually stop the duplication of apps?

I just found out that the person doing it created a new account and removed the app from the previous account which had a paid version.
