    Just skimming right now.

    Don't do correlations like this - you're bound to find a correlation:

    (1) Nothing fundamentally can be in the top right quadrant. There is no product that appeared last year with a TTOSA of 10000. Can't be. Adjust for that.

    (2) The bottom left is also bound to be scarce because open source wasn't much of a thing long ago, and long ago products that were quickly displaced by FOSS are potentially forgotten. In particular, the dead-since-the-80s proprietary inspiration wouldn't necessarily appear in the readme.

    With how messily intertwined these two measurements are, I hope the author is a lot more careful about his statistics than just drawing a line through that scatter plot.

    One mitigation for (1) could be to bake a cap into the scatter plot: Products where the proprietary founding was less than 10 years ago will be ignored, as well as products where the TTOSA is more than 10 years. That's quite restrictive, but I think that should cut off the data in such a way as to not find a correlation that doesn't exist: You're capturing all the products released in that timeframe, and you know about all of them whether they were replaced in 10 years.
