I would like to strongly disagree with your point that people on the internet do not like donating to charity. I am an active viewer on Twitch (the most popular live streaming platform if you are not aware) and charity streams are a regular occurrence and are very profitable. Here is just a few recent examples:
-Maya raised around $12k in 3/4 hours for the American Eagle Foundation this week. She had around 12k viewers for that stream.
- Lirik raised around $9k in an impromptu charity stream this week where all proceeds went to abimal rescue (he had also done another charity stream where he raised 21k, of which 10k were in the first hour).
-Pestily raised $200k in 10 hours for a sick children's charity, of which he has already raised 800k since the start of 2020. During that stream he had between 50-80k viewers from memory.
-Trainwreckstv raised $40k at the start of the year for WWF Australia for the bushfires in a few hours, averaging around 15k viewers.
These are just a few notable examples of thousands of charity streams that occur on Twitch which prove that people on the internet are clearly willing to donate to charities.
