I'm basically fine with people hosting anywhere that allows you to at least download a file without requiring one to use Chrome, or an external application that has to be designed specifically for said file host (which basically rules out MEGA and Box in that case, then). It's more for the sakes of this community targeting configurations that are considered 'long obsolete and unsupported' by many websites so for accessibility reasons, it seems rather ironic to support using file hosts that explicitly break on anything even slightly 'old'.
Dropbox, Google Drive, MediaFire and Yandex.Disk are all okay in this scenario - at least all of those you can simply 'wget [url]' somewhat easily if you desire.
Naturally, my favourite recommendation is set up your own FTP/HTTP server, turn directory indexing off in Apache and host from a server you rent online or even your own device but that isn't always possible.
