Who knows what people will cook up if they are unbridled. Of course limiting users also breeds innovation to overcome the limitations (youtube-dl is a good example), but artificially creating limitations for the sake of money, isn't a good argument IMO.

If you want applications for the future, don't limit it.

- Docker and other VM images - Backups - 4K video editing synced to shared NASes when working from home - Build and content syncing for gamedev when working from home

4gbit/s is still slow enough for me to spend minutes syncing a mere 100GB, even if I can exclusively saturate that link and not share it with a roommate. That's smaller than some blueray disks and many steam games in their compressed/compiled/processed states for a single platform - no debug symbols, no built object caches, no source assets. It's not uncommon for me to resync a significant portion of that due to mass rebuilds, poorly handled content refactoring, or just switching projects when my local disks (mechanical, SSD, and otherwise) are all full.

Who knows. I was excited to do icecc over a gigabit WAN on those "cloud" servers.
