Looking at their 2019 financial data, BYU lists $10.3M of "revenue" (14% of the total) as coming from a part of tuition being allocated to athletics
That makes it appears that BYU athletics made a profit that year (listed as $1.1M), but that's only due to the portion of tuition that students paid and that went to the department. That obscures the fact that BYU (like pretty much every other athletic department) loses money unless subsidized by something (student fees, tuition allocation, government support).
Saying masking seems to have made people think I meant it in a way that they were conniving and trying to hide it, which I'm absolutely not saying. I'm just saying that at the surface it looks one way ($1.1M profit), but that deeper digging shows something different (only due to tuition money subsidizing the costs). I honestly can't think of a university that doesn't do this
