In a sense, if it's a small server you wouldn't need donation drives. But once you hit the size of MTS2 or PMBD/MATY, one person can't afford it all.
That's exactly what I am saying. Look at how the large sites that take uploads from large numbers of creators have shifted the cost burden from creator to downloader. Many people will obviously think that is only fair - so I am not knocking it. Just observing.
I pay $7 a month for space I choose to use to enable me to share what I make (you can pay less but I have very good quality hosting). No one told me to make it or share it, so I don't want to ask anyone else to pay my hosting costs. A metaphor: If I have a houseparty and invite guests, I expect to pay for the food and drink according to what I choose to give my guests, not charge them for it. The nice thing is my guests will invite me to their parties too, and I won't have to pay for what I eat there, either. So in the end it all evens up. If one of my neighbors couldn't afford their own party, I might tell them to invite their family to mine, and celebrate there (eg sharing my space with other creators)
To continue the metaphor, the large sites are as if instead of having a normal houseparty in my own home, and letting my neighbor invite her family, I let *all* my neighbors invite their families. Then I find my house is no longer large enough and I cannot afford to buy food and drink for all the guests who will come. I now need to hire a hall, and get caterers in. Now I can't afford it myself, so I have to ask the guests to pay for tickets or put money into a whip-round.
