They most likely asked for permission first and if they didn’t they will be copyright striked. If you want to us someone else stuff you need to ask permission first before using it.
Just because they have it doesn’t mean they have permission, if you’re going to use someone else’s logo you need to ask for permission or they can legally sue you in real life.
Adding on to what Sir @Country_RBLX was saying, the graphics logo isn’t related to roblox (excluding the fact that it is for Roblox). It legally belongs to it’s creator, ( asimo3089 I believe.) Therefore you cannot use it with out (explicit) permissions as Sir @grilme99 says aswell.
It’d be the same for stealing someones brand name or something like that, and yes you can get sued in real life. Be careful about these things, a simple mistake can cost you.
Don’t use it in your game unless you ask or have permission. The owner of the logo (goes for all games) could sue you or anyone who uses it in their game without permission.
