in my opinion it will be a little complicated because there are many types of companies or internet services so they will continue to compete for customers unless the one controlling them is the same person.
but such a theory would be difficult, because even people would think that if there was only 1 owner or type of provider.
if there are several internet services provider , price will not be expensive. each companies will give best promotion to their customer by issuing many discount for new installment. in my countries there are many company, and they try to attract user from competitors by releasing interesting promotion.
