- They have to buy Siacoins for using it. And I know it's easy, but I also know everyone isn't used to do such things. A lot of people who would use this product aren't familiar both with the tech and the whole crpyto world.
- They never heard about SIA ! This thing need to be putted in front of people who have already the need for such product. You can have the best product in the world, if nobody know about it, it'll stay in the shadow forever.
Recently had a "coffee machine" chat if I can say so, with an engineer. Those points have really cooled him down

About the first point, @Hakkane said this few pages before :
Pixeldrain (
https://pixeldrain.com/) is a service for large files sharing, currently free. The author is implementing Sia as a backend and will allow a free tier like now, and a paid tier for very large files. There are at least 2 more projects that I am aware of, but they are personal communications, so I can't disclose information, sorry.
So it might be a solution
