If you have an iPhone, you can’t text on your computer unless you have a MacBook

Sync was widely regarded as the best third-party app for Android. I preferred a different one, but I don’t think it’s shutting down for another 10 days, so you can always open it up and try it

I haven’t owned any Apple products since the ipod nano in 2005, and have only used Linux, specifically Ubuntu), since 2008 (then my sophomore year in college) for exactly the reasons your colleague spells out. I try to use open-source software whenever possible. Apple is the most closed-source vendor available to me, so I have no intention of ever using their products. When I was a teenager / early 20s I would espouse the evils of Apple to anyone who was nearby, whether they wanted to listen or not. Now, I cringe at the memory of that behavior and let people live their lives.

I do see why your colleague connected the dots between your two separate arguments, and I do see where they’re coming from. The idea of Freedom of Scientific Information and FOSS do have many parallels, but I don’t think you need to beat yourself up over using Apple vs more open-sourced software. I don’t really think there’s anything particularly wrong with Apple devices, and when my current laptop starts to go I might even consider one of their offerings. But my needs are simple enough that Ubuntu has always worked for me. As far as phones, I just like Android better (and more of it is open-sourced).
