Why has Democratic Party TV disabled Super Chat support? T.T

I want to provide a little help to the Democratic Party, but
Super Chat is not working on the 7 o'clock Prodo live stream or even the current parliamentary policy meeting live stream.
Why are they blocking voluntary Super Chat support from party members and supporters? T.T
I can guess the intention behind it...
But wouldn't it be even better if they collected it and used it for good causes?
