How would everyone feel if every carton of a dozen eggs at the grocery store only contained 7 eggs? And the grocery store manager said that the farmer was not paying the store, so it was OK to not provide all 12 eggs as written on the carton?
Now, I am the customer of my ISP. They advertize speed tiers, and I choose to pay for one of them. I am paying for that speed grade to access the internet at large. This is an INTERNET Service Provider, after all, not an INSERT_BRANDNAME_HERE Service Provider.
I expect to be provided the speed grade that I pay for, under contract, for anything within my ISP's boundaries. I understand that my destination may pay for a different speed at their end. But I do expect to receive what I pay for on my end.
Some cray situation where everyone at my ISP downloads something very large at the same time might have some impact, but this should be a statistical rarity, with my ISP building enough infrastructure to have a very high statistic of meeting its side of my contract with them. If they cannot, or do not plan to do this, then they should reconsider their advertizing and what speeds they offer.
To make i ta matter of policy to not deliver on their side of our contract is problematic. If they offer in their advertizement a 50Mbit/s speed tier, then they should do their utmost to deliver on that. To artificially degrade that is counter to their advertizement of 50Mbits/s speed that their customer signed up and contracted for. To do that for the reason of "because I said so", just isn't right. I paid for a dozen eggs, yet you feel no expectation to give me more than 7 in this example.
I just don't see how that can continue in the long run. Eventually, more and more people are going to notice some eggs missing, and start wondering why they are paying the price of a full dozen eggs to get that. Once the masses realize the problem, there's going to be a huge outcry and demand for things to be made right as they seek out an honest grocer. I truly wish the dishonest one would be held accountable, but surely they have planned for a fine someday and are making sure that this future business expense is already being passed on to their customers today, yesterday, and the day before that.
I think the Half Fast advertizements going on right now are somewhat ironic...
