I think it also important to note that it wasn’t just the pricing itself, which was indeed already heinous, but that the rate calculation changed. It used to be a rate per user per app (apikey+oauth) but they changed that to just the per app … that then has a multiplicative effect on the costs and makes the “free tier” they were talking about especially pointless…

It would be easy for an app to start at free tier … not have much growth through word of mouth but enough given the per app rates to push it over boundary points … and then be due a significant and unavoidable invoice in a couple of months…
