Bethesda's Creation Club has been a bit of a sore spot for the modding community. Okay actually it's been pretty contentious and you can see the fallout in, well, a new mod for Fallout 4 that removes the Creation Club news box that's now become a part of the launch menu.
A new update for Fallout 4 added the Creation Club News banner to the main menu, but shortly after modders created the No More Creation Club News. The mod is a pretty simple cosmetic change made for the PC version of the game that simply removes the Creation Club box. You will be unable to redeem the 100 free credits for the club Bethesda is offering as an introductory offer, but if you're already anti-Creation Club you're probably not interested in receiving those credits in the first place.
The mod, created by InAComaDial999 is already climbing the mod charts, currently listed as the highest voted-for mods on Nexus Mods (via PCGamer), and already has 15,000 downloads. The Nexus page for the mod will get you set up if you're interested in downloading it yourself.
Creation Club launched last month, but modders have rallied hard against it. This is in spite of modding being core to Bethesda games like Fallout and Skyrim (no mod support for the upcoming Switch version though). Still, I imagine Bethesda won't be backing away from Creation Club anytime soon.
