I’m asking this because one time, while browsing the GNU website, I noticed that some of the members’ emails had “gmail” on them!! And I asked myself how would that be possible?? And I think other members of the FSF had Gmail too. Why? Richard Stallman is against Gmail, so why would those memberse use it?? Would that mean I can use non-free software while advocating and loving free/libre software??
I personally do not think it is conflicting, especially when you consider how hard or impractical it is to completely avoid the non-free/proprietary software. Services like Gmail, YouTube, and Facebook, to name a few, have been around for a long time, and they have become so entrenched in our daily lives and social circles that avoiding them completely and all at once may be too disruptive. I’ve been using Facebook since I was in high school, and that’s also the platform I use to communicate with my closest friends. To suddenly jump away from that and expect my closest friends to follow me to the next major platform (e.g. Mastodon) is going to take a lot of effort and convincing, especially if my friends have people they connect with on Facebook and are not likely to move to another platform.
The same can be said for YouTube, even with their ridiculous anti-adblocker stance. People have become so invested in it that completely breaking away from YouTube would be almost impossible. Thankfully, that’s where services like Piped and PeerTube come into play.
I think what really matters is that people at least make the effort to utilize FOSS whenever and wherever possible. Whether that be a Linux distribution over Windows and Mac, or a FOSS alternative to one of Google’s or Microsoft’s products, or a federated platform like Lemmy and Mastodon, there are so many ways we can demonstrate our love and support for FOSS, and utilizing a non-free/proprietary service does not make us any less committed to FOSS.
Anyways, that’s just my two cents.
