That seems legit to me.
DRM content is usually encrypted and only decrypted through some proprietary plugins, so you have to agree to use these plugins if you want to watch these videos.
This is the same mechanism that Netflix and Disney+ use and it helps them by not letting you download movies to your computer.
More like effectively a paid-for VPS which, depending on where you live, might cost about €3/mo.
Configuration is all on your end and, to be fair, you may still end up on a blocklist since that’s just a way to bypass their VPN restriction and your IP will not show up to be a residential address.
