I would assume for bandwidth. If they are making a lot of transactions, during busy times, it might drain them a bit. Better safe than sorry I guess. Tho, exchanges should have enough to power up like 1k STEEM by themselves and save that for a better use.

Makes sense for Binance, but Bittrex has 4200 SP, and Poloniex 2100, so it doesn't seem like they would need it.

Well, I think that its time for STEEMIT INC to take a look at this and fix stuff up.

I have an extremely good guess about it - and it's not for badwidth. However I'm limiting myself to posting only twice a day so I'll send you a link for it only tomorrow .
