Hmm. I guess that works, too. I'm just a nerd and really like Free Software. Almost exclusively use it. My phone runs a custom ROM with just a few unfree apps and without Google services, all my computers run Linux. Even the internet router does, and my IoT smart sockets run Tasmota or ESPHome. I like the 4 freedoms and the culture behind it. I participate and regularly contribute. All of that is mostly personal preference. I guess I could as well live comfortably with using Google Drive, but I choose not to. Source-available software would allow me to look at the code, something proprietary software doesn't allow. But that's pretty much it. I often can't remix and share it as I like. I don't have the freedom to decide to use it as it pleases me. And depending on the exact license, I can't even invite my friends and family to use the services I set up...

It's just the line I draw. Either it provides me with the Four Essential Freedoms of Free Software as lined out by RMS in the eighties, or I don't volunteer to use it. I have no issues though with other people making sifferent choices.
