Look at the number of users here on the board and players overall. Its not even BG3 specific it happens even with full game releases. After the first couple of weeks the interest drops significantly. But feel free to prove me wrong that there is as much interest in the last updates as in the first hot-fixes.
Just look at the all time peak or average numbers per month and the current numbers.
