The reason it makes sense for G+ isn't because of antitrust concerns, but because it would be consistent with their "do no evil" mantra.

Regarding the second point, I have no problem with Google saying these are "beta" APIs, subject to change. Their services carry this same label. As a developer I'd much rather see their full API stack, with some marked as beta, rather than a much neutered API.

With that said, I'd like to see the same for WP too, but with Google they have set a public position of doing what is right even if it is against their corporate interests -- I want them to uphold it -- not just when it is a PR win.
