We use the same form as you, companies are a singular entity and the correct form would therefore be 'Microsoft is always wrong', not 'Microsoft are always wrong' (I too disagree with the sentiment of the comment by the way). However, we aren't too precious (or careful) about it in much of our writing over here and you will find many items of company information that refer to a company using 'are' or 'we', it's considered in some circles (corporate comms usually) to be a friendlier, more inclusive way of refering to an organisation.
The title also seems incorrect to me. 'Suck' is not a term widely used over here (at least not by anyone over the age of 13) so maybe I'm not familiar with the colloquial use of the term, but given that Windows 8 is singular, shouldn't the phrase be 'Windows 8 sucks', rather than 'Windows 8 suck'? I should add that having used Windows 8 a little over the past few months I happen to disagree with this sentiment too; I like it and I think that on a touch device it'll work well.
