I understand that fact that Google is growing fast and big. But as long as there are alternatives (to google's services) and Google is not buying up all competition, there is no reason to say Google services are evil - as it ties you down to Google.
The fact that many people worry over the fact that Google pries into your activities when you use Google (most are machine algorithms) seems to me to be unjustified, since if you are privacy minded dont use Google's services and instead use the already existing alternatives. Google is not doing its data colletion surreptitiosly. Most of its data collection activities are known and disclosed by Google and also specifically stated how long they keep such user data etc.
