Buddy, billionaires don't care about whether you shame them.
But they do care about the prestige of looking charitable.
It makes far more sense to play along and let them feel like heroes if it means the next tragedy gets $100k.
Consider this: donation shaming contributes to a cost/benefit analysis.
Consider that Taylor Swift could donate $100k for every single tragedy that occurs this year and be no worse off.
But that would get her more bad press than it's worth. People would say "why does this tragedy get $100k when its obviously far worse" or "The amount of people affected are more than this other tragedy, why are you racist?" Etc.
So, they stay quiet, and even then people get shamed for not using their platform to speak up.
If you actually give a shit about seeing the most amount of money going to help people, you should realise the path forward is to lower the bar to access, and make donation as beneficial as possible to the people donating.
Holy strawman
