How to tweak ridiculous copyright transfer statements

Today, I added my name to the list of researchers taking a stand against Elsevier on The Cost of Knowledge.

But the parasitic behaviour of publishers has irked me for a long time. For example, this is how I handled a ridiculously absurd copyright statement Springer wanted me to sign back in 2009: I reduced the rights transfer from an exclusive one to a "non-exclusive right to reproduce and distribute the article", and I changed the obligation to link to Springer to an option - "the author ... may add ... an acknowledgement of the original source of publication". Springer either never noticed these tweaks, or they did not mind.
