No one else mentioned network effects. I have a shared family calendar for my wife, son (readonly), and myself. Also my son's scout pack used a shared calendar for his meetings. And I was the treasurer for a volunteer org and they drank the goog koolaide top to bottom. Its not just using owncloud calendar, but making it 100% interoperable all the time with the rest of the network, which has agency and as per the linked article they change stuff when THEY feel like it because they're SaaS, not when its convenient for me to develop and test interoperability. Finally it a very low level tool. I have a nice set of unfortunately expensive Wiha screwdrivers on my lab bench. That does not mean I'm dependent on Wiha... in less than a half hour I could have dramatically inferior yet more or less interoperable products from Craftsman or no-name Chinese or other on my lab bench. Or, this was typed on an old Dell keyboard, but as a very low level tool I'm not controlled or defined by such a low level tool... its just my primary Model M is plugged into something else at this moment so I'm stuck on an inferior mushy keyboard.
