One person can hold 1 or 5000 addresses, it doesn't make sense to draw pretty plots from it.

Indeed, and there may be strong financial/legal incentives for doing so. Similarly, many developers may all be employed/funded by one organisation, and multiple clients may share large amounts of code (and be unable to avoid accepting large changes made to the upstream project).

So, while I appreciate the great effort to quantify the level of decentralization in the cryptocurrency space, I think the article mostly just exposes the subjective decisions being made by people who make claims about decentralization. Even that could be a big step forward for debating these technologies, though.

> We certainly don’t argue that the particular choice of six subsystems here is the perfect one for measuring decentralization; we just wanted to gather some data to show what this kind of calculation would look like. We do argue that the maximum Gini coefficient metric starts to point in the right direction of identifying possible decentralization bottlenecks.

It seems the article is mostly to reframe the discussion.

I haven't even seen bad versions of these measures compiled before. Debating the choice of bucketing strategy (and other such) is a massive improvement.
