Some people avoid large providers, since large providers have approximately no incentive whatsoever to keep you, specifically, as a customer. I.e. large providers will happily raise their prices, alter the deal, throw you under the bus, disable your account, delete all you data and then refuse to talk to you. They can do this because, when they look at the big picture, you don’t matter to them. And since doing this saves them some money, they all do it.
