En réponse à Luk.

First of all i apologize for my bad english.
I would argue that it is a bad idea to implement monetisation as a feature in peertube for two major reasons.

1) Monetisation is a complicated and tedious process. You have to find a payment provider, negotiate contracts and what not. And still then the problems never stop. Let's look at librepay where from one day to the other their payment provider stopped working with them because they had a lot of smaller transactions. This is a hassle that requires fulltime commitment to the cause. It is not something an instance admin could do besides maintaining the instance itself.

2) I think one of the major benefits of federation (like peertube or mastodon) is that you can be a digital nomad. If the peertube instance i am hosting my stuff on changes in a way i do not endorse i can move everything to a different platform and people would still follow me. Tying monitization to a specific instance could result in a hostage like situation where i, as a content creator, would like to move to a different instance but are not able because they for example are not taking part in monetisation. This is a general problem for youtube by the way. A lot of creators are kept hostage besides all the youtube shenanigans because they can not migrate their audience to a new platform (not a real problem with federation) or they depend on the monetisation system youtube has established.

As conclusion i would propose that the next version of peertube supports external forms of monetisation for example by displaying large buttons next to the video if the content creator opted in to add payment information like paypal links or their librepay, opencollective, patreon, etc. account. This way the whole system would stay flexible.
