It literally just is not. Attention and money are categorically different things. If you want to argue that directing your attention at something is somehow equivalent to spending money on it, then be my guest. But you have not done that. You have shallowly asserted that they are identical with the verb "is". They are not.
Their attention leads to him getting money through sponsors, ad revenue and merch sales. I don't think that makes the viewers "charitable", but it does mean that money is flowing into Mr Beast's bank account.
