If you replaced 'listen' with 'care', you'd be 100% correct.
Sadly this was an affliction they developed during Alpha and never managed to cure themselves of. I haven't played since mid summer, yet coming back today, I see some of the same bugs we encountered during the Alpha test that still haven't been addressed, yet somehow they thought expending resources on 'fixing' grenades was a logical development decision.
There are numerous issues they should have been addressing in order to improve the game. Grenades apparently were more important than fixing the chat system, fixing the nearly non-existent economy (They went backwards on that one), correcting bugs with random spawns that have persisted since Alpha, etc...
