it's because everyone is mindbroken by snipers being able to 1tap you in every fucking game for 20 years straight, which is an especially big deal in more recent genres like megasweat 6v6 hero shooters and extraction shooters and such.
moving like a sperg, to possibly avoid being headshotted by someone you can't see, is ingrained in our muscle memory. there's also a sense that it puts pressure on whoever is watching you, because it complicates expecting what you're gonna do.
in short it's due to the sheer autism of modern competitive games.
if you're asking why people weaponswap in Counter Strike it's because they're bored from having run the same routes on the same maps 6,000,000 times.
