Played a couple of matches already and I haven’t noticed. I don’t think it’s that big of a deal. The announcers need to relay information about events in the game, but you’re focused on other stuff happening and don’t really have time to think about their voices.
The JWST actually sits at a Lagrange Point (L2)
There is a good write up including video and animations to explain what where and why https://webb.nasa.gov/content/about/orbit.html
