I'm going to investigate this in further detail, I have a Raspberry Pi setup that could cause some issues but that is extremely unlikely, all it's running is a Samba share and a Pihole. My plan's connection speed is 70 Mbps so no bottleneck there. I've also tested to see if Bittorrent traffic is being throttled as well, I haven't tested exhaustively but I got barely 20 Mbps on an Ubuntu ISO that should've been downloaded at 50 Mbps minimum. Also, upload speeds have been 20 Mbps+ on all networks and devices, including I-ON.

So it seems that there is something wrong with my I-ON connection, not any of my devices or ProtonVPN itself. I've also tested out ProtonVPN speeds on an Idea connection, I get 20 Mbps+ speeds on it.

I've tested this across 2 Windows machines and 1 Android phone on my home network, and tested with all available free servers on ProtonVPN. I've been noticing for the past few days that my ProtonVPN speeds have been really bad, around 1 Mbps max DL.
