Hi @Mars_TheHuman,
That is one of the reasons for why it's not recommended for a standard user to do this, since it will void the warranty on the device, DRM security keys will be removed and so forth.
I haven't seen any promotion about this at least not in the market where I'm situated, but there are always risks with unlocking the bootloader and it's important to understand what it means to do so.
For more information about Open devices and so on, I would recommend that you take a look at our developer part of our forum that you can access on the link below.
