I like this idea. It seems to me that we are seeing more and more egregious examples of companies pushing their luck with how far they can exploit their customers' loyalty.

The difficulty would be in defining an objective "greed index".

I hope you're right that we're reaching a tipping point in customer attitudes. I find it depressing that companies seem to get away with this stuff so easily.

The greed index doesn't need to be objective, it merely needs to agree reasonably well with users' values. It seems plausible that users of such an app would agree well enough for it to be workable.

Alternatively, instead of reporting a numerical index report a summary of complaints made against the company. Downsides: more stuff to read; still subjective; maybe more risk of lawsuits from complained-about companies.

I listened to a Hanselminutes podcast with the founder of iFixit today - it seems like for electronic products, the repairability / planned obsolescence of products should be a factor in a greed index

I love the idea, but sadly I'm reminded of existence of sales and marketing. They'll game the shit out of that index, just like they do with everything else that matters.
