Community still decides ultimately, and I believe that Core will come up with a rather nifty yet temporary solution for the non-existent (yet) scaling problem that a lot of people have been bringing up from time to time to question the ability of the Core devs in handling bitcoin development. Also, a lot of promising fork proposals have been brought up to the table and so far, none of them proved to be the best one that solves the problem most people are bringing about, so yeah, this Bitcoin FS thing might go down that route as well.
Its hard to use Bitcoin because the blocks are choked down to 1 MB.
We wouldn't have so many forks if Core had not f'd up the network.
Bitcoin FS solves these problems.
How exactly would big blocks solve the scaling problem for bitcoin? Other forks have attempted the said approach to no avail...
