Strictly in all English-speaking countries, all commercial companies, charitable bodies, public authorities and any other kind of corporation corporation are “corporate individuals” (despite my tautology). That makes them strictly singular in the same way you and I are singular… but strictly is not idiomatically.
Idiomatically, plurality depends on whether we are referring to the corporation as a single entity, as in “Microsoft is the richest organization known to man” or some of the people who work for the corporation, as in “Microsoft have some great ideas.” Although “Microsoft has some great ideas” might very well seem more obvious, idiom doesn’t always fit the text-book.
Sometimes it’s either or both, as when it’s equally valid to think that “Manchester United has/have won the cup for a fourth time…” because on the one hand the team won and on the other, the members selected to play that day won.
Google is a fine example because the one noun might denote the search engine, or the corporation that owns the search engine, or some or all of the people who work for the corporation that owns the search engine, or any combination of those at the same time and in which of those cases can we imagine it not remaining singular?
There may be the odd idiomatic difference between American and British or any other country’s form of English and most obviously (last time I looked) many American schools did and most British schools did not teach topics like “container for the thing contained” much less its corollary, “thing contained for the container”.
Are we referring to the team or to the players and either way, are we using the team name to mean the players or the players to mean the team, or what?
Singular or plural, can we really “boil a kettle”? In a boundary we might; otherwise, clearly not.
Again, when we open one can and a number of worms crawl out, is the description singular or plural?
Equally, since that’s a different kettle of fish, does “that” refer to a single kettle or a school of fish - and even then, is that a singular school or a number of individual fish?
Legally, teams or corporations or governments are all, always, singular.
Idiomatically, context over-rides any such rule.
