They didn't need to trick anyone. They withheld knowledge. Every tech company agreed they could do whatever they wanted with user created data and the user had no rights over that data. No user was informed of the full extent of the consequences of agreeing to use new tech... or allowed to alter the 'agreement' tech companies offered the user. The 'trick' was hiding sales tactics that were illegal in traditional businesses, behind TOS, EULAs and unregulated internet space. We all know deep down inside that no man would agree to what big tech did, so the deal was made unintelligble to the user.
