An M1 MacBook Air is $999 and has a much better display, four times the battery life, it's faster and doesn't run hot.
* The MBA comes with 256GB which is not enough storage, especially since when you run out of space you have to buy a whole new laptop to get more. That's compounded by the high prices that Apple charges for storage upgrades. The cost of upgrading to a 2TB SSD and 16GB of RAM (just the upgrade, NOT including the base price of the laptop) is more than an entire Framework laptop with a 2TB SSD and 16GB of RAM
* IIRC the MBA only supports 1 external monitor. The Framework supports 4 external monitor at 4k144hz (I'd only ever need 2, but it's nice to have extra headroom).
* Ideological reasons I won't belabor
