I would think the questions need to be applicable to ALL the providers at the shootout, not pointed at particular providers, so you have to ask things like:
1. What are your local / international contention ratio's and why?
2. Why are all your services so expensive? Why are you prices not comparable to similar offerings internationally? Even in other developing countries, without the existing infrastructure we have?
3. Why does you services limit usage via both shaping and capping when they serve the same purpose?
4. Why are the imposed limits for both capping and shapping so ridiculously low, and expensive by world standards.
5. Why are some services introducing caps on local traffic? This is unprecedented anywhere in the world.
6. Do you not consider it unethical thal ALL of your ads promise first world multimedia services but in truth deliver glorified Dial-up? (Rather than "broadband" lets rather say non-dial-up services.)
7. Why then do you denegrate and brand users who try to use these services for such as, "Abusers"?
8. Why is Mauritius and Senegal more advanced than South Africa, when we've had the technologies for longer and better infrastructure?
9. Do you believe your service is currently capable of making the internet more accessible AND Affordable for the average South Africa, not just for the wealthy.
10. Currently the cost of "broadband" is such that the service itself is a luxury. However the true value in BB is in content delivery, of which currently in South Africa there is little or non. How do you intend on stimulating the content market in a non-restrictive, affordable manner?
11. What do you thing is the best way to grow local Internet Usage?
12. Do you know you're all greedy leech scum? (

Um. okay, or maybe to rephrase : Are your companies aware of the publics opinion of you? Does the overall negative perspective of your companies not bother you?
