Yes, and the browser should be enough in many cases, but the holder of that information tries to force their app on everyone.

One of the most annoying examples of that for me is accepting a new connection on LinkedIn from my phone. I want to tap on the link in the email and be done. Instead it redirects me to the store, I close it, try again. Sometimes it works, sometimes I give up and do it later.

Another example is Facebook. :)
