I stopped using Dropbox a long time ago (though switching cloud storage services is not trivial!). My point is a more general one, that today's tech companies can't just be, they must expand and expand.
To butcher a quote from Grandpa Simpson:
“I used to be ‘the target customer’, but then they changed what ‘the target customer’ was. Now I’m not ‘the target customer’ anymore and ‘the target customer’ seems weird and scary. It’ll happen to you!
Yes, I’m also not their target customer for all those add on features that I don’t want… I would be using a different service if there was one with similar or better syncing capabilities that works as well as Dropbox…
You’d probably be better off using a different service if it bothers you so much.
