Nothing to do with nerve, and everything to do with self interest.
Do you think Google (or any organization) is capable of shame? I could extend your question to "How could Microsoft whine about Google shutting down its Youtube API access, while Microsoft was shaking down Android OEMs with secret patents and forciing them to make Windows phones as part of the (secret) settlement?" or "How can Apple ramp up its ad products when it rails against Google/Facebook ads?". The answer to all of those questions is self-interest.
People don't seem to agree with you. Google screwing up it's own messaging strategy for a decade and then whining about the consequences of their own decisions shows a lot of nerve.
> Google has been unable to field a stable, competitive messaging platform for years and has thoroughly lost the messaging war to products with a long-term strategy. At least some divisions inside the company are waking up to how damaging this is to Google as a company, and now Google's latest strategy is to... beg its competition for mercy? Google—which has launched 13 different messaging apps since iMessage launched in 2011—now says, "It's time for Apple to fix texting."
