Depends on if they change their business model. Right now there search engine is clean, and ad free - even if they do get funds from the sites on the right hand side. Their webmail is, bar none, the best webmail there is. You don't even need to use it as webmail, you can use POP3. They recently extended it to 2 GB from 1 GB. What is there not to like about google??? Unless they change, which I don't think they will, they won't be hated like Wintel if thats the sort of comaprisson your making.
Look at Mozilla, when will people start hating them - and FireFox? Unless they become some POS company that charges 30$ for their browser, then why would people start hating them?
