I already alluded[1] to the incentives for the host to minify their JavaShit, et al., and you would have a point if it wasn't for the fact that performance otherwise isn't significantly different between minified and full source code as far as the user would be concerned.
I'm not talking about the browser's performance, I'm talking about the network bandwidth. All that extra JS code in every HTTP GET adds up. For a large site serving countless users, it adds up to a lot of bandwidth.
Somebody mentioned negligible/deleterious impacts on bandwidth for minified code in that thread, but they seemed to have low certainty. If you happen to have evidence otherwise, it might be informative for them.
