It's not about the workarounds, those are symptoms and some of the reasons this is a thing in the first place.
The face that sentiment around Facebook is generally negative but most still use it is testiment to the monopolistic powers these discussions are all about. Could people migrate to Twitter or some other social network? Sure, maybe. Are they? No. Why? Everyone thought Facebook was a blip in a string of Friendster, MySpace, etc -- but boy they've had staying power despite the low switching cost we thought we had on the early internet. How is that not worth exploring to the fullest?
We don't actually know if these issues affect most people. What would Amazon be like without their Amazon products crushing their third party partners? What would Facebook be like without WhatsApp and Instagram? What would Apple be like if you could plug your weather app of choice in vs their acquisition and likely destruction of all current iOS weather apps? Will Apple nail the DarkSky integration and make a top notch user experience? Almost certainly -- that's not in question.
All of that has a ripple effect through the economy and right now there's purely discovery happening and I still haven't heard one good reason why this discovery process isn't worthwhile, outside of its lack of effectiveness, from the very people who seem to be against any kind of change.
