By pricing the service as free, they price out all competing services
offering something for less than it costs to produce is illegal in some countries. and while being generous can be ok, doing so to keep out competitors is the reason why it is or should be illegal. it should at least be illegal for companies that have a monopolistic market share.
It does seem like they have destroyed most of the competition. I was frustrated with the ad-blocking the other day and looking for a video but the whole first page of links was all youtube. I guess that's why they are starting to crack down on adblockers since people don't have as many other places to go now.
