If the only thing the word "monopoly" does is spark a discussion about the word then why use it? Why is it so important that Google be a monopoly for their behavior to be bad? Do we really have no other words to describe business practices that we don't like?
There are other words, but it is a bit of a mouthful.
Because of these exact issues, the way that I describe the situation is usually as follows "Company X has significant market power, and is engaging in anti-competitive actions".
I have yet to have someone object to that definition.
Because it is generally accepted that monopolies are bad and that not-monopolies are ok. It is much easier to sell the simple idea that "X is a monopoly, so split X", than to make a long case that "X does Y and Z which meet ABC definition of unfair use of market position, bla bla bla, so split X". Conversely, for a company in the wrong, it is easier to say "Of course monopolies are bad, but we are not a monopoly!".
