We must all consider the possibility that sweaters who don't deposit and suck bandwidth and resources from MA/FPC/NEVERDOODLE have become a liability and seen as a drain on the bottom line.
That isn't exactly new, but I would guess that MA are particularly worried about it now due to the expected influx of all the new players. I expect the logic to be something along the lines of:
"Want to play for free, sure! You can log in and maybe explore a bit, wander round and chat to your friends. Want some more interesting clothes than OJs - deposit. Want to try shooting something - deposit. Want to try mining - deposit. Want one of these cool new vechiles - deposit" etc etc etc.
They brought in the Calypso Gateway to start the newbies off and give them a taste for the basics.
It seems like they have now made sweat mineable.
My guess is that at some point in the not too distant future, the sweating tool will be removed from TT, sweat will be auctionable, and there will be lots more BP drops that use sweat.
This would close off sweating for the new players, be start of the long slow death of sweating, and quite possibly encourage interplanetry trade.
Not sure if I like or dislike this yet, but to me it doesn't seem quite so crazy/fail as a lot of other people seem to think.
Time will tell I guess.
