Simple. We let them get away with it. Compare:

“Your PC is out of date” “Don’t be stupid, it’s only 2 years old and still works fine” with

“Your phone is out of date” “OK I’ll buy a new one”.

There needs to be a lot more of Answer A to Statement B.

Oops! Thank you :-)

I once got rid of ants by leaving a small pile of sugar out for them.

I like to think the ants that found it took it back to the nest and said “hey guys look what we found!” then got “don’t be so stupid! humans never do that! It’s obviously a trap, don’t ever go back there”
