Showing that they've accepted a few hundred thousand is far short of showing they've accepted
millions. For the facts presented all we know was there were only three years these companies made
any donations to the EFF.
If I gave someone $1 today, $10 the next day, and $100 the day after, would you then assume at the end of the year I gave the person hundreds of millions of dollars? Clearly I'm increasing this by 10x every day, so obviously this should continue in perpituity, right? Or maybe these were three one-off things, and it would take further analysis to determine I only actually made these three contributions?
I don't know the EFF took millions from Facebook and Google. They might have! But the data given doesn't prove it, and extrapolating it is only a little less crazy than the extrapolation above. There's guesses, and there's facts.
