This comment thread is about how the author doesn’t seem to realize that the motive of these services has changed in response to fewer and fewer users wanting a sync solution versus a backup solution.
It's definitely not "fewer and fewer users wanting a sync solution" and instead "more and more computer users we can sell something to if we pile features into our overloaded app".
There's a criticism in there that I share because I miss when things were more modular, but I also understand and appreciate the value and opportunities that modern tech is bringing to people.
The back and forth chaos of progress and foundation-building is important but frustrating.
That's exactly what the article author is saying.
