No. Actually, for as long as i've been involved in helping M&A at Google, they have typically turned them down by keeping some regular company page working, and redirecting all the other domains to Google.com homepage. IE what they did here. There are a few cases i can think of where the domain no longer exists, it depended on a lot of things. But basically all "plans" i read was to do the above. At one point early in my google career, i believe pretty much all domains google owned but was not using redirected to google.com. I don't believe this is done any longer in general because people were using it to guess at what Google was doing :)
