I'd go further and state that "ecosystems" are evil as they erode competition. It should be easy to change products independently of each other, e.g. I should be free to choose between Apple iCloud or Google Photos for storing my photo library. Instead I'm forced to experience what you already mentioned: integration preferences on different platforms, network effects and so on.

Only direct product properties should drive users' choices, everything else just raises the market entry barrier for potential competitors.
