It is.

Not all user processes upload those files somewhere surreptitiously.

Of course operating systems should support that isolation (hopefully in some better way than the hell that smartphones are), but it's not like Telegram can blame the OS for this vulnerability.

Only if you have access to full source code, can audit it (including each update) and somehow can prove that it has no vulnerabilities. Otherwise one should assume that any application is potentially-harmful and/or vulnerable.

    No, that kind of audit is neither necessary nor sufficient. (A firewall works without application source code, and trusting trust means we can hand wave anything even with source.)

    Ok, at least if it has network access, but can you recognize that this was a vulnerability, and that you're talking of something only tangential to it?
