Because the tool you use is just part of the equation. It's same reason I use Discord, Telegram, whatever. You trade convenience for money, time or privacy. Sad

Because the tool you use is just part of the equation. It's same reason I use Discord, Telegram, whatever. You trade convenience for money, time or privacy. Sadly, I genuinely don't think that any of the tools you mention come close to Photoshop or Lightroom (Darktable is getting there but still misses a few key things for me). To be an open source advocate I have to only use open source software? How would I drive my car? Or use my phone? Or my TV? It's just not practical. I advocate for mostly open source server side software. I wrote a Masters dissertation on Linux and normal peoples interactions with the Linux desktop. I record a podcast twice a month (selfhosted.show) and edit it under Linux sometimes and sometimes on Mac. My argument, such as it is, is that the tool I use to build and maintain my open source infrastructure doesn't need to be open to allow me to further the open source agenda. Linux changed my life and I do everything I can to give back to the community.
