Hell, I’ve even seen people rip them off to fit 3 prong plugs into 2 prong extension cords. I’m sure it’s not safe, but I dont know why and why they would be necessary sometimes and sometimes not.

It’s a safety feature on electronics that have a metal exterior, to prevent people from getting shocked, in case the wiring inside gets messed up and touches the case. It grounds the actual metal exterior. I guess it’s only necessary if you value your safety, LOL.
How and why it works is actually really interesting!
