This is a disaster
This is a disaster for Aussie consumers. All iiNet customers will now be handed over to TPG - a company which would be famous nationwide for cheap and lousy service if only Dodo wasn't even cheaper and even lousier.
TPG promise that they will retain iiNet as an individual "premium" business. Yer right. That's code for "charge these suckers more, give them the exact same lousy service we give all our other suckers".
Australia has basically three sorts of ISP:
1: Major telcos with fair to poor service standards, highly questionable techical competence in some cases (e.g., the Vodafail mobile network, anything that has to do with Big Pond), long lock-in contracts, and very, very high prices. Telstra, Optus, Vodafail, various other-brand fronts for them such as Virgin (which is Optus).
2: Cheap price-price-price vendors with no technical standards worth mentioning, appalling customer service on a good day and none at all on a bad day, and prices that look attractive until you actually try to use the service. (Dodo, TPG, various others.)
3: Serious players in between those two extremes with generally reasonable pricing, and generally decent service. (Internode, iiNet (which now owns Internode), hopefully there are some others but I don't know who they are, if indeed there are any others left.)
Not happy.
