It literally wasn’t recommended by OP. I know nothing about that instance, just stating the (hopefully) obvious in this case.

I would also like the link to custom roms channels. I never used Telegram but may check it out since its something I am interested in.

I don’t really undeestand from this mail how is it not open source, but I am not well versed in licenses and technicalities either.

I am also genuinely interested in further explanation of this view.
