Don’t use Fedora myself, but it may not be a hybrid ISO that becomes bootable when written… so I looked and you are missing a flag
dd if=/path/to/image.iso of=/dev/sdX bs=8M status=progress oflag=direct

Some perspective from a user who’s been on Magic Earth for well over a year:
I found that Organic Maps and OsmAnd+ just couldn’t cut it at all for finding addresses, routing wasn’t super great (or intuitive), and otherwise rated very low on family acceptance as a replacement for Google Maps. I used Acastus Photon for addresses and frankly it’s not that much better and the workflow was janky and pretty useless when you want to plot route waypoints. Magic Earth was the bridge between fully de-googling and having a livable acceptance factor. So far I haven’t seen them doing anything they don’t claim (not getting in trouble privacy-wise), so I’m good.
I would say “privacy friendly” is accurate in the title - but this is not FOSS. Even so for those looking to de-google without losing utility, I recommend it and am glad it exists.
Edit: I wish some apps (looking at you Starbucks!) would use a default mapping engine like Magic Earth instead of expecing Google Maps on Android phones (Graphene, Lineage, Calyx)
Perhaps not. But the flag allows for direct I/O for data, bypassing buffers which can be overrun with certain size blocks, potentially causing dirty buffer depending on the machine being used. My understanding is that it’s “more reliable” for writing (especially on shitty USB Flash drives) and getting the exact ISO properly written.
But it could be useless all the same - I’m just pointing out that OPs command is not the one recommended by Fedora when writing their ISO. Also OP is less likely to pull the drive before buffers have flushed this way.
