You're acting as if the Estate won't release the song if it leaks when clearly they couldn't feel less bothered by leaks. Most of the songs they release are songs that already leaked and they didn't shut down any of those seminars after the big leaks in 2020. Leaks don't change nothing for the Estate.
As for the people who complain about leaks being on an album that's really just a small minority, there are people on multiple social medias who support leaks being officially released as there are a lot of people who wanted Night Line and Hot Street to be on Thriller 40. Most people blame only themselves for listening to leaks early and spoilling their fun.
It only sucks to the producer who made the songs but all in all it changes nothing. You don't have to make a big melodrama out of it.
