Hell no, but also don't mistake me for thinking that this was a good idea.

However, particularly when I don't understand a subject well, I try to take all reasonable-sounding claims seriously at first and give them some back-of-the-envelope analysis. It seemed to me that the original claim was that Blue sales couldn't replace ads, but it seems like the numbers are close under some reasonable approximation.

I do agree that this move is likely to drive many users away from Twitter entirely, but a short-sighted company could still think that an acceptable tradeoff if they're having trouble selling all available advertising space.
