There are mostly software and applications for mobiles and laptops that asked users to accept the terms and conditions before using the app. Many people continue without reading that terms because these are usually very long texts and paragraphs. If there's the title for checkbox of terms/conditions is I have read and accept the terms and conditions and user tick it without reading it. Then it is a sense of lying and haram the use of that software?
No, it's not. Especially given the length and complexity of these terms and conditions.
It's basically the collective responsibility of watchdogs and regulatory agencies to make sure that software companies don't abuse the trust that's given them - it's not simply the individual's responsibility, though of course that matters.
People generally click through on them as they trust that watchdogs and regulatory bodies do a good enough job so that they don't have to worry too much about the terms and conditions, except in unusual circumstances.
So no, it's not lying. If anything, it's sensible.
