I have seen this claim a few times, but noone ever gives any real reasons as to why.

A monopoly born through a superior product is not the same as a monopoly born through anti-competitive practises. Noone is forcing or coercing anyone to use Google+. Facebook and twitter are only a click away, and both are massively more popular.

Could we say the same if Facebook launched an email service? Or if Twitter launched some sort of search engine?

We're not talking about a mere monopoly, we're talking about exclusive API integrations in, hypothetically, an OS with majority market share. That's not something that has historically been tolerated well by courts.

They haven't done a whole lot about MS (which is basically the definition of this behaviour) though, even looking at Europe.
