Indeed, I see them as middle of the road. In my very anecdotal perception, by order of 'less reliable' to 'most reliable' in terms of product continuity, of the big 5 my list goes as follows: 1. Apple (Aperture, "Smart" features from OSX absent from iOS, APIs that force almost complete re-writes, generally culling of PC/corporate friendly products such as Server etc). 2. Facebook, seems like they experiment a lot (which is good) but too often fail to label things as beta. And they change 'features' way too often for my taste (I seldom use their services so far, at least on a personal level). 3. Google (Google Read for news strikes me as the biggest loss personally, my news were never the same afterwards as I never considered putting in so much time carefully selecting RSS feeds etc. if they could go away just like that; eventually I don't even read most news anymore). They have a less-than-stellar record on mobile apps, but then again that's a moving sector where it's hard to be consistent over "LTS" kind of periods. 4. Microsoft, but at this point I have to commend how much long-term support they put into most of their products, sometimes it's even too much to have to put up with legacy features that hinder modern paradigms (particularly on Windows 10, ofc). 5. Amazon, simply because I've yet to encounter a case of product/service being put out of service. I wonder who agrees/disagrees around here.
