1. Microsoft. This is wrong since while it was mostly impossible back then to buy a PC without windows, it is quite possible today to not use google. In fact not using google is easier than using google (you can skip typing google.com into the address bar)
2. Comcast. This is wrong since in many markets comcast is the only internet provider. No markets exist where bing and yahoo are inaccessible.
Really this is just EU punishing google for getting too big. Unfortunately for EU, even their own ridiculous (IMHO) protectionist laws do not have anything about a company being to successful for their liking. I imagine this will be a huge money and time waste for the EU, but in the end they have no real case. Google owns google.com and may display whatever it wants there. Until someone forces EU citizens to use google, or until bing and yahoo die, they are not a monopoly, even as per EU's ridiculous (IMHO) definition.
Google does not owe foo.com or bar.org or baz.info any place in their results page, unless is so chooses. And foo, bar, and baz are only there at google's mercy. Just like EU cannot force _YOU_ to include content _I_ want on _YOUR_ page, no matter how successful and how non-european you are and how unsuccessful and how european I am, it has no real power to force google to index foo, bar, and baz, or place any content of theirs (snippets of text and links to their pages) on google's property that is google.com/...
