At least until very recently (and to a certain extent even today still) many different companies would have the same name and similar branding despite being in vastly different industries. Good names are hard (something any programmer should be familiar with) so it really just doesn't make sense to not use a name or domain that would work well for your brand just because a previous company existed at one point in the past.
