So I've spent the better of the past five years campaigning and cajoling friends and family to use #Signal. And overall, I've been successful. Only holdouts is my DND group and some in-laws.
Plot twist though! I've fallen in love with using my #Librem5. But the lack of native Arm64 support by Signal is a literal encumbrance to a full dump and jump. I believe one could say I've been hung by my own petard!
