I switched from Google Photos to Filen. I'll only be uploading new photos to Filen, since I have about 30GB of stuff on GPhotos, and I'm on the free tier of Filen, but it's doing the trick!
I also switched from Joplin to Cryptee, since it seems more stable and it means I don't need to risk my (admittedly encrypted) notes being mishandled by Microsoft or Dropbox.
I upgraded my BitWarden encryption settings and changed the account's email address from Gmail to Tutanota.
I switched from Element to FluffyChat, as the Apple's "App Tracking Transparency" box appeared to list a few too many options under "Data Linked to You".
I have followed PrivacyGuides' recommendations for Linux distros, and I am now running the following on my laptops with full disk encryption:
openSUSE Tumbleweed + KDE Plasma (Wayland)
Arch Linux with linux-zen + SwayWM
Fedora 38 with SELinux + MATE (X11; Wayland support is being worked on)
Have a look at Neocities (a successor to Geocities). My website is here.
You can also have a look at the rest of the Fediverse. There are some cool accounts on Mastodon and PeerTube.
For that true "old web" thing, have you ever heard of gemini? Take a look. My capsule on gemini is here, but you will need a gemini browser in order to see it.
