I believe my answer was a summary of a previous answer from HT, though it was so long ago that I can't be entirely sure.
I think HTC didn't want people being able to de-tune range / country etc. Necessary for community interaction.
This is an entirely different issue. If you squelch someone they should remain squelched. Being able to leave the arena and rejoin, If i hear the same noise again within minutes of squelching them I'm like

. These are the people that make your ears bleed or cussing on range etc.
So

perma squelch. Fighter Ace had it HTC can do it
