That's what he said. They didn't forbid it, but they also didn't mandate it be allowed.

In contrast, Apple did forbid carriers to block software updates in it's contracts with them.

It's a matter of who you think your customers are.

Google sides with advertisers, device makers, and carriers and not it's end users.

I fail to see the relevance of Samsung not updating their phones to Google not wanting Android to be forked. If Samsung had forked Android, they still wouldn't update old phones.
