Why is Talking pictures TV not available on Sky Stream but is available on other sky platforms

[Paul4434]

As TPTV is our favourite station i am very disappointed that we cannot get this channel on Sky Stream, yet friends can get it on other Sky platforms. There seems little point in us having Sky by the looks of it 🤷‍♂️

Talking Pictures have previously said they would like to be available on Sky stream but Sky has to invite the channel to join the platform. It's not like the satellite platform where any channel can join.
