In this context, I mean that in two ways (but mainly #2):
1) macOS has a feature (Spotlight) where I can search all of the files on my entire computer with a simple keyboard shortcut. >99% of the time, the result pops up within a second. I use that feature literally dozens of times each day. With LaTeX installed, I got a lot of results that are not relevant to what I want. In hindsight, I should've just disabled the indexing of the files in my install directory.
2) My computer (at the time) had a 64 GB hard drive. As a result, I was straining against the limits of that pretty hard. Uninstalling MacTeX (I believe that was the distribution I used) freed up at least 2 GB. I'm not sure why there's a discrepancy between your quoted figure of 1.2 GB and my experience.

In addition, ShareLatex's UI was far superior to anything available for OS X (at least, at the time).
My primary interest is in making myself as productive as possible. If using non-libre software gives me significant gains in productivity while not being unreasonable with their licensing terms/costs, then I will use it. That's the same reason I am using macOS. By using this proprietary piece of software, I do not have to tinkle with the inevitable strange bugs that pop up with the various libre options and therefore I am allowing myself to be the most productive I can possibly be. Every time I have tried using a libre OS, I have experienced some kind of bug that's simply impossible to diagnose and solve.
In sum: the value proposition of non-libre software is increased productivity. I highly value productivity. So, I am willing to make the tradeoff. I recognize and accept that if everyone does this, the world is worse off. But, I am selfish and therefore am willing to make the tradeoff (to some extent; my willingness to tradeoff is not infinite).
Sidenote: I could (technically) not throw away my freedoms by hosting my own instance of ShareLatex (as it is, now, licensed under the AGPL), but that's highly inconvenient and I have no interest in being a system admin. Again, this goes back to the idea of increased productivity by using "proprietary" services.
So, behind all your marketing buzzwords, you're trying to portray GNU/Linux software as buggy in contrast to superior Mac/Windows, which has, interestingly, long been a FUD and a lie propagated by Microsoft. This suddenly takes me back to halloween documents and "real cost of 'free'" because you're saying exactly the same thing, only in 2016 (on halloween eve!).
Like many others, I've been using GNU/Linux since ~1997, and been totally happy overall, and I can vouch it's nothing like you're trying to portray.
You may, of course, value your freedoms less than the conveniences you find in Apple or SaaSS programs. You prefer trading your privacy and freedoms for bits of conveniences, and that's the way you chose to live. I did hear you the first time. No need to reiterate, as this is not about your personal feelings or the "values" you found here and there (and no offense, but frankly I don't care about your personal feelings or anecdotes).
I'm trying to make a point that goes beyond your "productivity": this line of though shouldn't be advertised as a good thing due to the fact that it eventually hurts us as a society at large (see the references in my previous posts).
