Yeah you can usually turn it off, but it's still annoying.
I bought a mechanical keyboard that I otherwise really like. But it came with full RGB on it. I can disable the rainbow pattern it does by default with the software, but the manufacturer cheaped out and didn't include onboard memory for settings. I didn't realize this would ever be an issue so I didn't look for it when buying... The end result is that every time my computer turns on, my keyboard looks like it's trying to summon a leprechaun, and that only stops once Windows has loaded the software up in the background.
A lot of people speculate that Microsoft would try to work around the UK's CMA ruling against the merger by not publishing any Activision-Blizzard games in the UK.
To me that sounds like bullshit that wouldn't fly, especially since MS has so many of their own offices in the UK and their own critical businesses that could be impacted too. But I'm not a lawyer so take my "that's bullshit" with a heaping pile of salt. Although I haven't seen any lawyers speculate the above either, so take that with a similar pile of salt too. But that's the reasoning behind the statements to that effect.
