I've swung over the last few years from thinking it's manufacturers' fault to realising that most of the fault here lies with the linux project itself. They're the ones who have normalised constant churn and thus needing to keep drivers for hardware, sometimes many years old, up to date year after year or even month after month. After seeing the churn mentality affect everything mainly spreading from web dev circles to the rest of the ecosystem, it's hard not to identify that trend as having been the norm in the kernel for decades.

I've only come to realise that blaming manufacturers for failing to keep up to date with a constantly moving target was totally unfair.
