Do you have any source on this?

I've worked in Aptoide, they aren't a virus company. They even spent a lot of resources fighting virus but that's always a cat and mouse game and given the amount of resources they have vs amount of users that can publish an apk (everyone) it gets hard.

If you think they are manipulating the published apps, you are free to fork the Aptoide client on github.com/Aptoide and create your own version.

That's precisely why Google wants the average Android user with uncertain tech knowledge to use the app store. It uses Google's immense machine learning and ops resources to fight malware and malicious apps.

It would be more like if Pirate Bay sued an ISP for blocking end users from accessing their site. Aptoide makes it easy to find and install the apps; it doesn't create or modify them.

Is there any evidence of TPB actually doing this? Because they absolutely should.

Exactly this.
