There have been some reports by people who visited a Fairphone community event that the bootloader would be locked as part of licensing conditions for Google components, with a fee payable for each unlocked device. Apparently this fee was factored into the FP2 price, but is being handled differently for the FP3 as the vast majority of users has no need for an unlocked bootloader. If all this is true, we don’t know whether this means that Fairphone intends to charge for unlocks, or whether they’ve accounted for e.g. 10% of users requesting one and will hand them out free of charge when requested.
