OC Can someone ELI5 the situation with Red Hat and CentOS?

I've been hearing about it a lot over the last few days, but I don't exactly understand what's going on. What's going on with Red Hat, and how does it affect Linux users?

Okay so, introduction!
Hi kids, you might remember me from such posts as Doing Things Out Of Order and I'll Do That Next, I Swear.

I'm Lizard! I'm sort of in the #cdrama/ #cent fandom (#MDZS, #sleuthofthemingdynasty, #SDC) , and a multifan of damn near most of the #CQL actors. Favorite hobbies include #WangYibo (anything/everything), saving unorganized pics on my phone, and yelling about Marius #wangzhuocheng
Will also yell about #XiaoZhan, #LiBowen, #SongJiyang , #DarrenChen, trails off...
