why is my club tag now completely capitalized?

I've had the same clan tag for well over a decade now 'RrGE' and now it reads 'RRGE' with no option to change it back. I saw somewhere by an EA employee that this is SUPPOSE to happen and all clan tags will be capitalized. I would just like to know why and maybe get more people to see and care about it cause things like this do kinda matter when you run a team, no matter what yall are competing at
