Been using a degoogled LineageOS phone with all apps being exclusively FLOSS. My favourite free alternatives to proprietary apps and services must be Lemmy (Jerboa) for Reddit, ArcaneChat and Matrix (Extera) for Telegram, Fluxer for Discord.
Which ones are your favourite?
Interesting. But from reading the description I don’t see any advantages over Thumb Key because the latter also has two-handed layouts that can be seen in screenshots of Flickerboard. What do you find better in Flickerbourd that in Thumb Key?
