Ugh.
a) The "giving pledge" I think is the WEF/UN/crap (run by the people who did the convid scam). Yeah, bill melinda gates foundation garbage.
b) eyeroll to seeing the 'buzzwords' "sustainability", "inclusive capitalisim" (what), used by some of the other 'plegers'... and lol - read this letter by the canva people, the planet is not "dying" (fyi, planet has been around a lot longer then they have), but funny.
If one has incredible wealth - it is much better to CREATE your OWN organization and direct those funds - instead of giving it to some random strange. Many of the so-called charities/foundations/etc actually do a lot of evil (more accurately, the executives at the top). So instead of 'giving away' your wealth - create your own organization and do something with it. SOOOOOOO very stupid.
And yes, agree with the above post. Pay creators, don't steal from them.
