While it is absolutely true that he cares, I think you are selling his long term plans short. The primary growth factor for the channel was reviewing phones with the repairability / endurance focus, but somewhat recently he expanded to topics such as plugging abandoned oil wells which are leaking methane and wheelchair mobility issues. From what I understand he has a couple similar things in the pipeline.
my biggest annoyance is his plugging or advertising stuff too obviously
I think so: https://www.youtube.com/watch?v=7R71uDa3DNw
What? That still happens with so much CO2 and climate change outrage and people literally gluing themselves to roads as protest?
Ok, did more research: "In 2021, fugitive U.S. methane emissions from abandoned wells were 295 kilotons—equivalent to 8.2million metric tons (MMT) of CO2 with a 95% confidence interval of 1.4 to 25.1 MMT, the largest uncertainty range among the nation’s largest sources of methane (US EPA 2023)." https://www.doi.gov/sites/doi.gov/files/orphaned-wells-metha...
So the estimate would range from 0.12% to 0.4% (for 8mmt and 25mmt respectively).
If I remember correctly he first built her a wheelchair to go hiking in. That was kinda the beginning of their relationship. I think there was also a stair climbing wheelchair involved at some point, but that could have been a sponsored thing rather than something he built.
He’s also been working on an electric humvee. So he’s a lot more than just the channel where he scratches and tears apart phones.
