There are multiple reasons:


 * 1) Software these days often tend to "call home" to its creators. Collecting all kind of personal info, mostly by hooking the browsers, in order to deliver personalized ads (Even if you use an adblocker, info would still be collected, you just wouldn't see the ads.)


 * 1) Malicious software

There are more reasons unrelated to trust:


 * 1) You might want to check which algorithms were used by an application.


 * 1) You might want to modify the application (Matters for example in modding, it's a lot harder to modify a closed source game)


 * 1) You might want to port it over to another operating system.
