It's increasingly getting harder and harder. Recently I was trying to watch a TV show with my friends using a self-hosted Plex server, which was located in one of my friend's house, connected via a gigabit, albeit residential link. Another friend was using LTE internet at that time. He couldn't watch the show, because his connection was so slow, but when he did a speed test the download speed was good enough (100+ Mbit).
Turns out the mobile carrier was throttling connections to select IP ranges to about 1 Mbit (we tested that with a few other IPs). I reckon it was to cripple peer-to-peer protocols. So I guess it's a matter of time until you will be allowed only to connect to certain IP addresses owned by the biggest companies (AWS, Azure, GCP) and nothing else.
