1 is clearly ethical, someone has to install an app specifically for this in exchange for money. Your ISP might not like it but since when does anyone care about an ISP ToS? You're not allowed to pirate movies either according to your ISP.

Some ISP terms are more reasonable than others. Not running a commercial data operation on a residential contract is one of the more reasonable ones; they clearly have commercial contracts available, you know why people who run lease-your-upload-bandwidth-for-money software aren’t choosing them. Both the people running the apps and the ones encouraging them to do so are questionable here, and the former may not be fully aware of the consequences (I personally know someone who got throttled then eventually banned by their ISP this way) whereas the latter would know.

Btw, no I don’t pirate movies (I do sometimes torrent content I already bought because I don’t like the official player). Again, your ethical standard is different from mine, and mine different from people who don’t torrent at all, for instance.
