I hate barrel socks because I think they're lame. When I started airsoft as a 14 year old rental player, I had been shooting already for 6 years with my parents, and I had also been in cadets for a few months where the first thing we learned is firearm safety. Even as a rental, you can bet I was making sure my gun was safe and not pointed at anyone because it was muscle memory at that point. Also, the guns I run now are gas guns, so if the magazine is out, the gun literally can't fire, so I hate having to put a barrel sock on before heading back into the safe zone because I've been practising weapon safety for literal decades.
However, I also said earlier that I really don't trust airsofters around airsoft guns and wear my eye protection from the moment I arrive to the moment I pack up and leave. With some of the mouth-breathers I've seen rock up to various sites and events, even just in recent history, I can see why sites are starting to use them.
I hate them, and I hate that I have to use them, but I understand why they're needed.
