I think it's a fair assessment, since setting up a self hosted solution generally costs money and may not be as safe/secure as something Google has. I probably wouldn't host my own solution to most things if there is a version available that isn't too costly.

Currently I avoid Google as much as possible because I don't want them to have my information in exchange for a service; I'd rather pay some money for a service that won't siphon my data and use it for various, advertisement based purposes (it's not surprising but it's kinda terrible that they put ads on a device you paid a bit of money for). The reason I stick with Facebook is that there isn't as much of a solution otherwise, but I do try to use alternative messaging apps (Line, Wechat, Kakao, iMessage) when possible.
