This is ridiculous, none of them would have changed their prices if MWEB didn't make this announcement. Every time MWEB comes with a new price, all the others jumps on the bandwagon (not that they have a choice).
What bothers me though, is the fact that MWEB is now in control of pricing, they've got the entire market by the *shorts*. If they decide to no longer pass the savings to the consumer, the others will probably do the same.
Truth. That's usually why regulation of some form is almost always needed.
What compounds this factor is that South Africans have in general been starved of data capacity and having only recently had the prospect of affordable uncapped, everyone is downloading everything they can find just for the sake of downloading (especially new users, admit it, all of you did). Once people get their binge, the average usage will decrease and the speeds can then be regarded as exactly that, instead of data transfer potential. I believe then will we start seeing even lower prices.
