Yes, I understood that. There are specific OS for Kodi like libreElec, that make it easy to have support for lots of codecs etc. I don’t know if any for specific to Jellyfin, but the Jellyfin App has a better UX than Kodi.

Kodi is a great Linux client. But that’s not what OP wants, the jellyfin app is a nicer UX experience.

There is lots of web based guis. These are accessed on a separate device on the same network (or internet). These use very little resources, all the rendering is done on the client web browser.

You are right, TOS isn’t the law. However businesses will try to trick you with this technique, especially if they don’t think you have any legal support. You can’t commit a crime just because the victim agreed to it, no amount of contracts negate this. Employers often pull this trick to force employees to accept illegal practices.

The person hosting and publishing the code may have never agreed to the TOS. So can’t be bound by it. They also can revoke their agreement, and no longer have to comply with it. However, continued use of the businesses web services likely requires agreeing to the TOS and this plug in may be using the businesses web services to make the plugin work.

They are often sold to non-tech people as fire sticks.

There general use case is:

1. You buy a fire stick from Amazon.
2. You give it to someone that ‘hacks’ them.
3. You transfer money to an account and are provided login credentials.

The ‘hack’ is just enabling side loading on the Amazon stick and downloading an IP client. Takes two minutes and is easily done, but people charge £50 for it. You can do it yourself if you already have access to an IPTV provider.

The difficult thing to do online is get access to the IPTV provider to purchase such a service. They don’t have any public online presence. They manage and sell their services through group chat apps like discord, telegram and some lesser know equivalent apps. The online way to get access to them is through someone you know.

Refering people to these services is actively encouraged. The providers often offer discounts/free periods if you referral makes a purchase.

The use of these services in the UK is so endemic that football channels now frequently advertise VPNs. Because it encouraged by the vendors of these IPTV sellers.

These services are not legal. So there is little recourse if the quality of service is bad or they sell your account details to someone. They also don’t spend much on infrastructure, so you the streaming quality is often limited to 720p and will struggle to serve during sporting popular sporting events.

No one is going to offer you it on here. Most people in this sub will be able to get better quality downloads for free. They also don’t want a public record of them using or distribution such service.

I don’t use them and don’t recommend them, I also don’t like live sports which is their biggest selling point. As live sports is very expensive as so much is broken up between different legal providers.

If you don’t know anyone that uses them, you’ll have to make some friends. Best place is sport events/pubs.
