Its not as bad as in the US I think, but yeah, most of the laws are actually (literally) written by corporations. I wouldn't call them puppets, but EU corps have an outsized influence on the outcome of the process.

I don‘t know about EU laws specifically, but national law in Europe is often written by lobby firms in favor of their corporate sponsors. In Iceland for example the main corporate lobby is called Viðskiptaráð, and they brag about the high percentage of laws they write passing at the parliament (in 2007 it was like 90%). I don‘t think things are much different in the rest of Europe (maybe just less obvious due to size differences).
