Its amazing they could get something so tiny to be a replacement for full desktop it would be better if Raspberry Pi's got back to focusing on cheaper prices rather than greater performance. Very few people are going to use an RP4 for a desktop due to much better alternatives being available for not too much money. Arduino fills the gaps for microcontroller. RPs sweet spot would be a full fledged linux desktop (i.e. access to massive existing code base) --- but for less than half the current price. Although it's usage as a desktop would be more limited to light server loads rather than daily driver it would allow for far more widespread use.

Good step for privacy but Cloudfare is a US based company. Like every other US based IT company (or Chinese for that matter) they would have no choice but to hand over their data and/or put in a backdoor for the US government on request (And it could all be hidden behind a National Security letter) Does the FF implementation allow users to easily point to whatever DoH server they want/trust?
