The counter-argument here is Popcorn Time (https://en.wikipedia.org/wiki/Popcorn_Time) which brings together search and bittorrent with a nice UI and makes piracy a bit too easy.

Or Firesheep (https://codebutler.com/2010/10/24/firesheep/) which made impersonating someone’s facebook account a breeze by sniffing their credentials which were sent in clear text (eg. on cafe wifi) and showing them in a UI and made stealing credentials a bit too easy, leading to wide calls for broad adoption of https everywhere.

Or Dropbox, which the nerds derided as pointless “because I can build my own”.

It’s fuzzy and individual, but there’s a qualitative difference - a tipping point - where making things too easy can be irresponsible. Your tipping point just happens to be higher than the average.
