Living in South Africa, and not being able to afford the expensive non capped internet~ this will have a devastating affect, since I normally purchase a 2gb bundle each month and sometimes, if I used it to fast, a extra 1gb ( just for surfing ).
If osu starts using my bandwidth, to share beatmaps, I will be capped much faster each month and probably will be forced to stop playing all together, since my current internet options are not cheap.
We are however planning on moving in the next few months to Pretoria, one of the bigger cities that has ASDL available everywhere, with ADSL I can easily get a 5gb bundle each month ( for the same money I'm spending on 3G wireless atm ) , where top-up doesn't cost a fortune either, then this might not be such a big problem, but if we end up not moving ( since this is in the planning stages ) osu will become a expensive hobby.
In simple terms, we pay for how much we can download, not our internet speed, any South African can confirm this. :<
So yes, I have a big problem with this.
did some math
R389 = $52.64
is what I pay for my 2 GB bundle each month, without top up.
Edit
I'd really like to see a disabling function, even if its only for people who have a valid reason, I cant dream of not being able to play osu :<
