re 2. Or one which only looks mutually beneficial, but only benefits Google in reality.
The biggest argument I've seen is that people don't like that they aggregate the data you give to them.
This goes to the broader point though that Google wants to service the end user better based on their feedback (most sites are too big/load too slowly), so they created something simple that gives end users a faster, better and cheaper (lower mobile data cost) solution.
In fact Google seems to be moving faster here because companies keep creating large websites to serve rich content that users find annoyingly slow.

There are also many people that actively support Chrome. Does it mean that Chrome dominance is therefore beneficial to the future?
