Apple doesn&#x27;t allow an app to &quot;download code that alters the application inner workings&quot; so extensions are a not possible.<p>This can be seen on the following shot: <a href="http:&#x2F;&#x2F;i.imgur.com&#x2F;faxbdBK.png" rel="nofollow">http:&#x2F;&#x2F;i.imgur.com&#x2F;faxbdBK.png</a> from the iOS Review Guidelines located at: <a href="https:&#x2F;&#x2F;developer.apple.com&#x2F;app-store&#x2F;review&#x2F;guidelines&#x2F;" rel="nofollow">https:&#x2F;&#x2F;developer.apple.com&#x2F;app-store&#x2F;review&#x2F;guidelines&#x2F;</a><p>This is Apple with its silly policies preventing competition again. I have no idea how a lawsuit against these practices has not happened. In the meanwhile you can vote with your wallet and use some other operating system and&#x2F;or donate to efforts that fight against such practices such as EFF, Mozilla and others.<p>We can have a better mobile internet than what Apple offers...
