I think DarkTable is as powerful if not moreso than Lightroom but Lightroom has AI image processing tools that will get things done quicker.
The whole of software dev is dominated with open source softtware. So like PostgreSQL, text editors like Lapce or Zed, KVM/QEMU/Virt-Manager, torrent programs like qBitorrent, VPN like OpenVPN or Wireguard. Pretty much all the video game console emulators. For a while you would get Linux game ports that would use proprietary wrappers but eventually WINE would become better anyways. Don’t know if there’s a proprietary software better than QGIS for that. I love Distrobox and Boxbuddy. Git.
Web browsers based off Chromium or Firefox, OBS, Handbrake, VLC, ffmpeg, image magick. Krita and Blender are competitive with proprietary software. I think the latest Pinta is solid as a paint.net analogue. Audacity is super popular. Ardour for more complex things. Kdenlive isn’t as good but solid enough for the vast majority of people in my opinion.
Topaz Gigapixel is top but Upscayl is good. I always liked Windows Task Manager but on Linux I think Mission Center is just as good. None of the open source stuff competes against Topaz Video AI in my experience
KeepassXC password manager. At some point I stopped using winrar and was all in on 7-Zip and Peazip if not just using the Linux file roller software that the distro came with. I’m happy with Jellyfin over Plex. There’s Kodi. Over the years I always see people use draw.io
I’ll keep an eye on this. Maybe even sub for minimalist usage. Currently use Proton Unlimited and probably at around ~200GB usage for storage and active use the VPN and email. But something fediverse is more interesting to me. I doubt it can suitably replace Proton for me now but it’s at least cheap. Nice to see cloud document/office stuff. Proton still doesn’t have a Linux sync application so that’s a weakness. Less sensitive stuff I’ll use Firefox sync for passwords but that Chrome web browser integration I think is a major feature for the Google ecosystem
I know a lot of people are opposed completely to crypto but for privacy services I would prefer paying with crypto. I prefer numerous options but I generally think Monero should be the minimum. Maybe trocador.app to support more. I will probably sub with a credit card to check it out and support though
