I'm new to this forum and to VR in general, but based on my past experience in other aspects of gaming:
You can safely use Download Link (workupload.com) , Download Link (mediafire.com) , as mentioned earlier and, personally, I've often used services like: Download Link (gofile.io) , https://dropmefiles.com/ , Download Link (catbox.moe) , https://tstorage.info/ , etc
To solve the problem with MEGA, you can use various VPN services. I find it closer and more familiar to use NekoBox (although there are far more analogs and possibly more advanced options, but the anime theme, you understand) - https://github.com/qr243vbi/nekobox

Well, now I just use a paid VPN for 10 devices and different servers, so downloading 100+ GB isn't a problem..
