Because they have f*cking unlockable bootloaders.
The availability or unavailability of unlockable bootloader is a debatable topic and I'm sure many users want to have it.
But please maintain sone decency when you're posting here on the community. You aren't dealing with HMD employees, but your peers. And they aren't really legally bound to offer an unlockable bootloader. So, we can only request them. The final decision is theirs.
Yeah, if unlockable bootloader is of prime importance for you, then you should consider buying a competitor's products. OnePlus and Xiaomi are quite open about it :)
