1/ Why pro-MAGA folks lost a few thousand Twitter followers (this is normal and has happened before). It's most likely:
a) a troll factory ceased its operations (bc Trump is over). Those accounts disappeared, thus the follower-count of the accounts they followed also drops

2/ Twitter had another enforcement-sweep against troll-factory accounts. Those accounts were eliminated so the accounts they tend to follow also saw suddenly drops in follower-count.
3/ Seriously, this isn't rocket-science. It happened a couple of years ago (I saw my follower count drop by over 5,000 overnight. It was just that the trolls had gone, not that 'Twitter was out to get me')
