I switched to Fogejo just by swapping out the image. So far gitea hasn’t been malicious with its trademarks now being owned by a private company, but I feel better using software that is more closely tied to a nonprofit. I see no reason to switch back.
Snappymail is simple and awesome if you want better webmail than roundcube, I switched and didn’t look back. I am also a big fan of native apps, I’m using thunderbird on my PCs and and Fair Email on Android, both of which I am quite happy with.
