I recently switched to them as a step to help de-Google. Will not go back to standard Android and push for /e/OS at the moment. I don't mind the extra weight and size between the Fairphone 4 and Pixle 5a.
Waiting on a purchase from Furi Lab to see if I can move even further away.
Issue with most phone hardware with Linux is that they are all past products that don't have G5 support. Looks like all the push for Linux phones is coming from the EU and stale and stagnate in the USA, hardware wise.
