I'm not saying it's not bad. Here it is almost OK, since it just a fixed object and its ideal, but imagine having [math]M\otimes_R N = MN[/math] as the notational convention for any suitably sided modules. Then I would find the author and extract some answers to the simple question "why do you hate your readers?". The morphism notation is absolutely horrible, and I hope the author got some feedback on it. That is probably the worst non-Mochizuki diagram I have seen, too. Not even the model category diagrams look that bad, but they actually have reasonable notation, so that may help.
