I feel the problem most people have when thinking about monopolies is if a monopoly produces a product that people like right now (e.g. they like the features, they like the cost), people don't see the monopoly as a problem and even will even defend it thinking it's great ("I love company X, they make amazing products, they deserve their success!").

The problem with monopolies is when the company decides to e.g. price gouge or gets lazy by not innovating. Companies can only really get away with this and survive when they have a monopoly.

Monopolies also kill competing products and deter other companies from even attempting to enter the market - so you might love the product of a monopoly right now but if the monopoly had never existed an even better product could be available today.

I think people generally love Google's products but it would be good to see more competition. The upfront investment you would need to create a competing search engine is prohibitively high so most companies aren't going to attempt to make their own.
