Are you trying to really understand how the thing works, or are you just looking for ways to dismiss the thing so that you can remain ignorant about it.

We’re talking about data transmission caps (as in, 1TB/month), not in bandwidth (as in 800MB/s) Also, IPFS is a protocol. The “cap” of the network is only theoretically bound by the amount of nodes running in it, but in practice it doesn’t really matter because the bandwidth of any single node will always end up being the real bottleneck.
