Something about the climate impact.
The climate impact... of space exploration? Would you be angry about this if NASA were doing these voyages? Space travel will be a fundamental aspect of the human experience in the distant future, and getting private companies and investors to start financing this kind of exploration is crucial for our survival as a species. If you're really worried about environmental problems, then you should welcome the opportunity for us to move pollution and surplus population off-planet, and you should support the technological innovations that will be necessary for us to get to that point.
Something about them profiting off the Covid and economic crises while billions have suffered the knock on effects.
Bezos has profited from the pandemic because he started a service that happened to be uniquely suited to giving people what they need during a pandemic. You don't have to kiss his feet, but there is nothing inherently wrong with "profiting off of Covid." The suffering billions you mention are the ones who voluntarily gave him his money.
Something about them going of their way to avoid taxes and spending that money on the vanity project of going to space in a giant willy.
I wonder, was the moon landing a vanity project? How about the Mars rovers? Do we have to wait until everyone on Earth has a two-car garage and a well-manicured lawn before we start investing in our future as a species?
This stuff is just so childish-- the constant whining and juvenile pee-pee references while highly intelligent, creative people put money into developing technology that will someday improve the lives of your grandchildren in ways you cannot even imagine. I will happily criticize Amazon for its influence in politics and media, and for its treatment of its employees in certain warehouses, but to thumb your nose at innovation of this magnitude just makes you sound like a Luddite. It's been decades since we went to the moon, and during that time our government has invested billions into pointless wars while neglecting space-- which is our future whether you like it or not. It is natural and beneficial that private interests would eventually pick up the slack.
It's really sad to see someone as smart, on paper, as you choose to get in the tank for this waste of oxygen every day.
Besides space isn't the future for the vast majority of Earth's inhabitants. There's a good chance Bezos and his gross cod lip girlfriend will be dead before they can escape the environmental hellworld he helped create.
