Yes they are obviously not perfect but they are at least trying to change something, while the massive cooperations just dont acknowledge that problem at all.

And the updates thing: Apple controls the ecosystem and are a huge company. They dont have to worry about manufactures for a processor or other parts not supporting it longer and stop giving it driver updates. Same with Samsung and especially Google. They are huge companies that can basically do what they want. They will be able to get a hold of drivers and firmware because they are a huge customer to the manufactures. And they only just started promising those long updates. Meanwhile Fairphone has been trying for years to support their devices that long and had to struggle because they are not a massive cooperation that can influence manufactures like that to the point they now dont use normal consumer grade chips but ones with extended support.

Other phones can be much cheaper because they don’t care about slavery or child labor in their production line and don’t support their phones that long
