It's obviously a matter of money, politics, and things beyond my imagination but I can't understand why Firefox didn't double down on Servo (and friends) for mobiles.

At one point there was talk about Samsung being a partner and Firefox/Servo becoming the default browser on the Samsung phones. Which would make a perfect sense, since every non-Apple phone gets its performance from multi-core SoC, and Firefox would be the only browser taking advantage of that. Now, after Google getting their hands slapped by the UE regulators, this Samsung/Firefox marriage could be even more fruitful. And yet, the Servo team got assigned to some pointless VR experiments, and it turned out Android was never a priority. Again: I can't understand why, oh, why.
