If a law requires a website to perform a duty towards its users as far as technically feasible what is the extent ? Does it mainly take care of financxial costs? Meaning is something that is possible using existant technology but very expensive and has huge impact ( negative ) on the other users if little mistake is made in the process reasonable and technically feasible just because it is possible to do so considering that not performing it will not cause significant damage given technical measures ?
"Technically feasible" takes into account cost of technology or not ?
